Claims

[Claims for Utility Model Registration] (1) A device for manufacturing pockets, bags, etc. from a tubular film web supplied by blown air, which supplies a laminate of bags without interrupting the manufacturing process. The bag is carried out and includes a gripping device for gripping the rear end of the stack of bags, a device for releasing the gripping device, and a moving unit disposed at the front end of the stack of bags, and the bag to be pulled out by the moving unit. In devices in which the bag stacks 11 are conveyed over longer distances, the moving units 20, 91 are designed as gripping units and remove the bag stacks 11 from the gripping device.
After opening L, the bag stack 11L can be moved in two steps relative to the forward movement of the bag stack 11L, so that the bag stack 11L is held by the holding device 14,
68 (with a time interval between two bags being cut one after the other) in a first stage and then moved, and thereby in a second stage the next bag for the formation of a new laminate. is characterized in that it lies on the rear end of the bag stack 11R just after being conveyed and forms a screen for the latter against the blowing air flow, and throughout the two stages the end 33; Devices 83 and 83a are characterized in that they press the rear region of the bag stack 11R immediately after being moved. (2) Utility model registration request that, when a laminate is removed from a laminate area, the end clamp is first released from the leading end of the removed laminate, and then the low traction member is raised from the removed laminate. The device according to item 1. (3) The low traction member is a wire having three vertical operating positions, namely a top position above the bags being stacked, an intermediate position at the stacking level, and a top position above the stack of bags. a lowermost position at a level at which the laminate is removed from the laminate area, and when in said intermediate position another laminate bag is first cut above the wire to already cut a screen against the air flow. 2. The apparatus according to claim 1 or 2, which is arranged to apply the coating to a laminate of bags. (4) The connection between the wire and the laminate tip clamp is made through a clamp advancing means, the clamp advancing means advancing the clamp without moving the wire, and further comprising another advancing means to connect the wire and the clamp. 4. The device according to claim 3, wherein the clamp is moved forward together with the wire so that the wire moves under the lowest bag in the stack of other bags. (5) means for causing the leading end of the bag laminate to be present at three levels in the stacking region at the stacking level and above the stacking level and at the required level for final removal; The presence of the tip of the already cut laminate and the presence of the tip of said other laminate when above the laminate level provides a screen against air flow when the clamping action of the wire is no longer present. Utility model registration claim 3 or 4 configured to be applied to the already cut laminate
Apparatus described in section. (6) An adjustment device comprising a latch capable of alternately closing and opening the stack end clamp and said means in the stacking area, and adjusting their relative positions when opened to stack bags of different lengths. The device according to claim 5 of the utility model registration claim. (7) A utility model comprising two traction members rotatable about a common axis and means for rotating the members about the axis, the two traction members acting as traction members for a continuous laminate. Apparatus according to registered claim 1. (8) The device according to claim 7, wherein the rotation means comprises a step motor for rotating the traction member via a half-rotation clutch. (9) A utility model registration claim comprising upper and lower finger sets in which the tip end clamp is laterally spaced apart, and a means for moving the upper finger set toward and away from the lower finger set. 8
Apparatus described in section. (10) The device according to claim 1, wherein the traction member is a wire. (11) 11 The device according to any one of claims 1 to 10, which provides a screen against air flow by cutting a plurality of subsequent bags.
