Abstract

Sewing machine doubled in its elements (table 5/5) which has been made with two motors, with two rotatable turrets and sixteen tubes with a second suction system, with new rolls for the stretching of the sock and a new system of turning inside out and expulsion when the sock is sewn. The two series of tubes (eight right and eight left) have been put at a distance (about 15 cm) sufficient to permit the regular work in the different phases. The eight left tubes of the rotatable turret turn clockwise with the base (A) on which they are fixed. The eight right tubes are concentric and in line with the eight left tubes. The right tubes follow the same circular clockwise movement as the left tubes and all this permits the different phases of the work.

Description

DESCRIPTION "Sewing machine for socks, stokinα. knee socks and similar " Technical Field

The invention concerns the textiles sector and, more precisely, it consists in a sewing machine modifying to sew socks, stoking, knee socks and similar with weaving edge-to-edge (double stocks): it has been made to be doubled in all its constitutive elements. In particular it had been made with a double number of tubes which work in a symmetrical way in the left side and right sight.

Thanks to this modifying machine and to the use of a socks sew edge-to- edge, it is possible to obtain the vantage to sew a double number of stocking in the same space of time used in the original machine.

Background Art

The machines which are in trade, had been made to be used for the sewing of the normal, classic, sock with a weaving which starts from a edge to the tip which ends with a rank of stitches, at the end the sock had always a tubular form and it is open at the tip. in particular the machine, of which the present machine is a modification, consists in the introduction of the socks in tubular guides from which they had been taken by mechanic equipment of dragging and they had been driven to the sewing. This machine sews only one sock a time. Disclosure of Invention

This invention concerns the textiles sector and, more precisely, it consists in a sewing machine modifying to sew socks, stoking, knee socks and similar with weaving edge-to-edge (double socks). This modification had been made on a sewing machine of socks tips made by the English firm Detexomat and in similar way by the Japanese firm Takatori, which consists in the introduction of the socks in tubular guides from which they had been taken by mechanic equipment of dragging and they had been driven to the sewing.

These machines had been made, as the others machines which are in trade, to be used for the sewing of the normal, classic, sock with a weaving which starts from a edge to the tip which ends with a rank of stitches, at the end the sock had always a tubular form and it is open at the tip. With the following request for the industrial invention in the name of Conti Andrea, title "System of socks manufacture, modifying machine for weaving and sewing" deposited in Florence (Italy) 30.07.1993, record number FI93A 151 , it had been possible the modification of the machine for the weaving and the sewing of the socks, it had been used for the invention of the double socks which had been weaving in the following way. Start from the edge to the tip of socks, the weaving which has a number of stitches at the end of the describes tip, weaving of a second sock to start from the end of this number of stitches with a second edge and a second tip.

Using this type of sock (pictures 1 , 2, 3, 4, 5, 6, Table 4/5), which had been described in this request of patent (Italian patent number FI93A 151), it is possible to reduce the works time about 50%.

The purpose of this invention is to give a modifying machine to sew the tip of handmade socks made in the way above describe concerning the double socks. In this way is possible to increase, on one hand, the productivity, the sawing of spun and, on the other hand, the general consumption and the less wear under which every product is subject the machine which is actually in trade (this machine had been modified by this invention), is characterised by a number of tubes which are open out their inside, they are collocated one by one on the circumference of the flywheel (Table 1/5, letter A), and connected to the motor of the machine itself.

The operator puts in the sock tube is opening (which is indicated with the letter B, table 1/5), the operator rolls up the extremity of the sock at the outside of the tube itself.

The sock put in this way, had been stretched inside the tube by a suction made by the machine, than after that the flywheel has made a forward movement, the sock had been stretched out of the tube itself by a rotating movement made by a roll put behind the tube (letter E, table 1/5); this roll grasps the sock that is jutting out and the roll trail it on itself turn it inside out. The sock had been stopped by two photocells in the wanted point (letter C, D, table 1/5). After that the sock had been pass at the cut and sew machine. By a roll the sock had been turned inside out again and expelled from the machine perfectly sew. This machine and this way to work, had been modified by this invention in the following way, presuppose the use of a double sock (edge-to-edge sock).

The machine above described, had been doubled in all its elements as you can see in the singular picture of table 5/5, particularly it had been made with a second motor, with a second flywheel and its tubes with a second suction system with new rolls for the stretching of the sock and a new system of turn inside out and expulsion when the sock is sew.

The two tubes series had been put in a distance sufficient to permit the regular work in the different phases (about 15/20 cm.). The 8 left tubes had been put on the flywheel and they turn in clockwise and they follow the circular movement of the base at where they had been put (letter A, table 1/5).

The 8 right tubes had been put at the inside of the flywheel by a correct cylinder. For the part which sticks out from the flywheel they have the same length of the other 8 tubes; at the inside of the flywheel the tubes sticks out about

15 cm. (letter A, table 3/5).

The right tubes follow the same circular clockwise movement as the left tubes and all this permits the different phases of the work. The difference is when the operator had put the sock on the left tube (letter B, table 1/5) and the two flywheels made at the same time a forward movement the right tube at that high (letter F, table 1/5, and letter B, table 3/5) puts on two inside rolls (letter C and D , table 3/5), these rolls are connected with a motor which push this tube at the inside of the cylinder (letter E, table 3/5), the rolls made it move in the outside so that it is near the left tube.

This coming closer is used because the machine could put half of the double sock on the right tube, so that the machine could work in the way that we describe behind:

1 phase: The operator put the double sock in the inside of the left tube which sucks it and stretches it at its inside. It rolls up the sock at the opening of the tube and a protuberance of the sock itself the right tube doesn't move from its position (letter B and W, table 1/5)

2 phase: thank to a first roll (letter E, table 1/5) put behind the left tube the sock had been turned inside out on the tube itself and stop at the wished distance by two photocells (letter C, D, table 1/5); in the same time the right tube had been stretched forward (letter F, table 1/5) and it had been brought near by a movement made by two rolls which had been put behind the flywheel (letter C, D, table 3/5). After that a second roll placed behind the left tube (letter G, table 1/5), pushes the half of the double sock on the right tube so that the tip of the two socks stop in the contact point of the two rubes. The two rolls had been connected at the right tube which had been put behind the flywheel; after a pre-establish time which is necessary for the stretch of the sock the rolls reverse their movement and take again the tube at their inside, the tube stop at the originally distance with the other (letter T, table 1 /5 and letter F, table 3/5).

3 phase: the two half of the double socks had been pushed forward on their tubes by a roll which had been placed behind the described tube (letter H, V, table 1/5), they are near the two extremity of the two tubes so that they can reach the cut and sew machine (letter U, table 1/5). 4 phase: the central part of the double sock, corresponds at the two tips of the socks, this part had been put in the inside of the cut and sew (letter Z, table 1/5) which cut and sew the two tips. δ phase: two rolls put behind the two tubes (left and right) which stretch the sock (letter K and Y , table 2/5) the sock had been stretches again forward. 6 phase: the two socks at this point are separated and sewed. The sock had been turn in out and socked in the inside by two tubes (letter P and S, table 2/5) which push then out of the machine one on the right and the other on the left, perfectly sew and turn inside out. The first phase became on the left part of the machine the second phase consists in a different movement by two parts of the machine, from the third phase to the other part of the work are the same in the left and right part. With the word "phase" we indicate a part of the work's process which consists in the forward movement of the flywheel (seldom two movements). All these phases above described, which we put in the subsequent order so that it is easier to understand how the work arrived at the end. But in fact all the phases work together: when the operator put the socks one by one (1° phase) on the tube, the machine is working on the other phases on the socks inside. The usefulness of this invention is that with the use of a double sock and this modifying machine (edge to edge sock) it is possible in the same space of time a double production of socks stockings knee socks with out make worse the work of the operators. Table 1/5 shows the frontal vision of the doubling of the tubes which became not 8 like the original machine but 16. They had been placed a part on the left and a part on the right.

Letter A shows the flywheel where had been placed the 8 left tubes it is present a corresponding number of 8 right tubes but in this picture is not possible to see them. Letter B shows the tube on where the operator put the sock ready to be work; letter C and D shows the two photocells used to stop the sock in the wished point; letter E shows the roll placed behind the tube used to stretch the sock at its outside; letter F shows the right tube in the moment of which it becomes near the left to allow the passage of the half double sock on the right tube. Letter G shows a second roll placed behind the left tube used to push the sock forward so that it can reach the right tube. Letter H and V show two rolls which push the two half double sock forward so that it becomes easier the entry in the cut and sew. Letter Z shows the double cut and sew and the letter W shows the right tube which corresponds at the left tube on which the operator works. Table 2/5 shows the back of the machine and in particularly the 16 tubes. Letter K and Y show the two rolls placed behind the tube which had been used to stretch again the sock; letter S and P show the two tubes on which the work stop; they sock the sock which is just sew and turn inside out. Table 3/5 shows the section of the right part of the machine, particularly the back of the right flywheel which in characterised by the tubes which are stopped on cylinders so that they can reach the position shows with letter B, thank to the action of the two rolls which had been pushed forward to be unite the correspondent left tube. Letter A shows the exceeding part of the left tubes which stick out behind the right flywheel; letter B shows the tube in the moment of which had been pushed forward by the rolls action so that is possible to unite then with the left tube. Letter C and D show two rolls which are connected with a motor so that when the tube is in the middle before push it forward and after a certainly time they reverse their speed and take it at their inside in the original position. Letter E shows one of the cylinder on which is placed tubes, letter F shows the tube in its original position after that it had been took in its original position by the flywheel.

Table 4/5 shows in figure 1 , 2, 3, 4, 5, 6, the different types of socks and stocking (double, edge-to-edge).

Table 5/5 shows the machine which is the object of this patent request for the improving.
