. This invention "relates to apparatus for printing, scorlng bendlng and slittlng of 7 paper stritps, more particularly to the making o-f sa ety strips for matches.

Safety strips for, matches are employed as a means forwpreventing the spilling of the matches from their container if the box is accidentally opened with the bottom side,

up and they consist of cardboard strips having their ends bent to fit against the end Walls. of the box against whichthey are held,

by the matches which they embrace, and the present inventionis directed to apparatus for scoring and bending the ends of the strlp for? printing the same and for cutting or thestrips to proper sizefroin a continuous 'roll, all bya single machine operation.

' The apparatus is designed to pass a continuous paper cardboard strip of a width corresponding to the length of the safety strip'through the machine which successively acts to score "the paper at 'the point of bending then print the safety strip, cut it off in predetermined widths, bend the ends on, the line of scoring, and assemble the ffiIl:

ished strips at the opposite end of the ma chine. I V

A drive shaft 4 is journalled in the frame 1 and carries a large pulley 5 which is driven by motor 6 to which it is connected the printing apparatus and an ink pot 8. In the head 7 is journalled a main shaft 9 which is driven through gear wheels 10 and 11 by the drive shaft 4. v

A spring 41 having a fish hook at one end projects in the path of the strips and prevents the same from being thrown back when the bending fingers 38 bear down on it.

After the strip has been bent, on its scored portions, it engages a pair of feed belts 42 which are positively driven by pulley 43 through a belt connection 44 with a countershaft 45 operated by the motor "6. The strips are engaged on their bent ends in the manner shown in Fig. 2 and built up in a stack at the end of the conveyor in the manner shown. They are subsequently removed from the stack and packed.

which imprints the proper legends thereon f in suitably spaced relation. The printed strip then passes between the cutting rolls 7 and 31 which aretimed through their gear-connection with the main gear to cut off the strips in proper widths, corresponding to the spacing of the printed'matter. The cut strips then pass to the bending mechanismithrough the conveyor rolls and 36 and are bent on their scored portion and fed into the belt 42 which assembles the finished strips in a stack, at the opposite end of the machine. 7

It is evident from the foregoing description of this invention that a combined scoring, printing, cutting and bending machine for finishing safety strips for match boxes as therein described, produces such strips in' frame structure, a pair of scoring rolls, a printing cylinder, a rotatable cutter and bendlng mechanism arranged in longitud1- nallyspaced relation and adapted to successively act upon an endless strip of sheet material in the order named to score it adjacent the edges thereof, to print it, cut it in predetermined lengths and bend the cut-off members on the line of scoring, means for feeding the sheet material from a" supply roll at one end of the machine, and means for assembling the finished bent strips at the other end thereof.

uniform quantities and in an inexpensive;

manner.

Although one embodiment of the invention has been herein described and set forth, it will be obvious to those skilled in'the art that Various modifications may be made in the details of construction without departing from the principles herein set forth.

We claim herein as our invention: 1. Apparatus for making printed strips comprisingthe combination of a printing cylinder, a pair of scoring rolls in the path of the sheet material, a rotatable cutter acting upon the material transversely of its length and having edges in angularly spaced relation, a conveyor for engaging the cutoff portions, and means for bending the-ends of the cut-off'portions' on the line of scoring, and conveying means for engaging the bent strips and for .stackingthem.

2. Apparatus as set forth in claim 1 in which the'op erations of the printing cylinder and cutter are coordinated to cut-01f the strips with the I printed matter suitably spaced from the edges thereof.
