According to second embodiment modification, pulsatile delivery device is bonded on and is in two of two product sections at opening side Between free edge.Pulsatile delivery device acts on now in the second product section so that the second product section beating in product Towards the second bag side shifting in the middle of opening.

However, the second product section is not acted in contactless mode according to the tensile force that this embodiment variant produces On.However, this embodiment variant is applicable to not exclusively open product, this product is according to the method according to the invention and device portion Open with dividing.

Suitable pulsatile delivery device is included according to the device for opening of this embodiment variant, it can be in conjunction with two products Open between lateral edges for partial two, thus to act in the second product section so that the second product section is by pulsing Transmission apparatuss towards the second bag side shifting, to open product.

For example, pulsatile delivery device can be rotary part, and it has at least one radially projecting rotate element, wherein Rotate element, during it encloses and is rotated about the center of rotation, is joined in the product partially opening, and collides the second product section, grabs Hold the second product section, and be located in the second bag side.Pulsatile delivery device itself can guide along the peripheral passage of closure, This path is channeled to product and opens in area, and is conducted out again.

By this program, the first bag side and the second bag side position relative to each other preferably keeps constant.That is, rotate Part not to two bag sides, do not exert one's influence by position relative to each other.

The rotation axiss of rotate element are preferably parallel to the plane being orthogonal to direction of transfer at this position, in this place, rotation Turn element to act on product.The rotation axiss of rotate element are preferably parallel to the rotation axiss of transporter.

Pulsatile delivery device it is particularly applicable to fully opening of product, and thus, the free edge of product section not only can be with It is separated from each other, and the second product section is also directed on the second bag side with surface based fashion.

According to 3rd embodiment modification, bag moves through along drive access and opens area, and simultaneously at least a portion around Pivot axis are pivoted on the contrary with direction of transfer.Acceleration acts in the second product section due to the superposition of two kinds of motions, And this second product section is guided by these accelerations towards the second bag side, and achieve opening of product.

Move along the first of drive access with regard to bag, bag can be utilized the bag opening facing out along arch drive access Guiding, so that bag can be brought into the position tilting with respect to vertical axis.This has the effect that, product is due to gravity In the middle of opening, the second product section, towards the second bag side shifting, and preferably against thereon, or continues against which.

As described above, bag is also suitably for fully opening the product that Part I is opened along the inclination of arch drive access, Or so that full opening of product is stayed open.

However, bag can also be carried out in a linear fashion along the movement of drive access, there is negative, positive gradient, or do not have Gradient.The effect mentioned being caused by gravity to be realized also by having linearly moving of negative gradient.

Device for opening is included for bag being brought the suitable device of the position tilting with respect to vertical axis so that second into Product section is due to gravity or at least by gravity support the second bag side shifting tomorrow, or keeps in this place.

Bag is moved through pivoting device to realize around the second of pivot axis.Pivoting action achieve bag with respect to Its current location is along the additional change of the inclination of drive access.Pivot axis be preferably fixing so that the connection of storage product At least one of edge is pivoted with direction of transfer on the contrary particular on the bag section of radially inner side or whole bag.However, Bag section including the radial outside particular on bag section for the bag opening preferably pivots along direction of transfer.

" being located at inner side " meaning is towards bag base arrangement, and " being located at outside " meaning is towards bag opening arrangement.

However, whole bag also always can pivot with respect to sender.

Bag preferably pivots about axis and back pivots, at the latest after product conveying (release).Therefore, around closure Drive access circulation during, bag experience one class swing or swing movement.As explained further below, bag is preferably again Back pivot, in case the conveying of product.

If the bag section being now currently located in inner side is pivoted on the contrary with direction of transfer during its transmission, the second product Partially due to the inertia force being applied to it and be resisted against on the second bag side in the middle of the opening of product.Therefore, inertia force pair Should be in tensile force.

Pivot axis can be located at bag opening and the region between the abutment element (specifically bag base) of inner side In, so that the bag section being located on the both sides of pivot axis pivots in opposite direction.

Pivot axis may be designed as physics pivot, and for example, may be arranged on bag.Physics pivot for example may be arranged at bag On side.Physics pivot for example may be arranged in the region between bag opening and the abutment element being located at inner side, or in bag In the region of opening, or in the region of abutment element.
