• the invention relates to a system for packaging a flexible band, in particular a textile band, placed in zigzag-shaped loops, and a packaging container for the system.
• the object of the invention is to improve the system mentioned at the beginning.
• the object is achieved by the characterizing features of claim 1.

• Claim 19 contains a particularly advantageous packaging container that can be used in the system.
• a configuration of the system according to claim 2 is particularly advantageous, so that the laying and packaging process can be carried out fully automatically without the use of an operator.
• the packing density can be improved with an embodiment of the system according to claim 3, since then the area of greatest tension, which is given by the folds of the loops, is not limited to the edge area of the band loop layer, but adjacent folds can be arranged offset from one another, whereby a substantial reduction in tension at the edge is achieved and a denser packing of the belt loops is possible.
• a significant improvement of the pack results from the design according to claim 4, since the length of the band per pack can be distributed evenly over the band loop layers and thus the individual band loop layers each have a uniform density.
• the tape packed in this way has the same properties over its entire length as a uniform position tension, which on the one hand enables better use of the packaging container and on the other hand ensures uniform properties of the tape for later processing of the tape.
• elastic tapes can shrink evenly in the packaging container, so that the elasticity of the tape is maintained uniformly over its entire length, since sections of residual stresses, material fatigue and elasticity Loss could be avoided. This enables a high quality end product and all of this with reduced personnel and increased performance.
• an embodiment of the system according to claim 5 is advantageous, according to which the laying device in the laying area has a pressure bar running over the entire length of the loop, which can be set perpendicular to the support plate for the position of the band loops and can be pressed against the edges of the band loops and prevents the loops rise up.
• the pressure bar is preferably equipped with a controlled drive in order to raise it during the transfer of the belt loop position and thus to facilitate the transfer.
• laying devices In principle, a wide variety of laying devices can be used, but a configuration according to claim 5 and in the development according to claim 6 are particularly preferred. Such a laying device is known per se and is described in EP 0062753B and EP 0778236A cited above.

• Particularly preferred here is the design according to claim 10, in which the drivers are finger-shaped and can be inserted vertically downwards between the push members from an upper rest position. This means that the belt loop position is under constant control during the entire drive-over movement, either the push links or the driver fingers.
• the system according to claim 11 is designed such that the support plate for the tape loop layer has brake strips from the laying device to the take-over device along the displacement path of the folds.
• the orderly transfer also serves the embodiment according to claim 12, according to which the band loop layer leading transverse to the loop layer guide strips are arranged on the support plate.
• at least one resiliently retracting stop member can be arranged in the take-over device in the area between the folds in order to push back, that is to say align, band parts that bulge in the take-over direction parallel to the loop position.
• a packaging container can already be arranged in the take-over device in order to receive the tape loop layer.

• the stacking device includes a rear wall serving as a stop for the tape loop layer to be taken over, a bottom which can be lowered to the thickness of the tape loop layer and an adjustable lid with respect to the bottom, which serves at least as an upper guide for a tape loop layer to be transferred.
• the lid serves as the upper limit of the stack and can also be moved parallel to the floor. The stacking of the tape loop layers is facilitated if, according to claim 17, a retractable receiving base is present in the take-over device, which is preferably formed from two bottom halves which can be retracted in opposite directions.
• the stacking device of the system can advantageously be lowered into a packing station, in which the stack of tape loops can be ejected from the stacking device into an assigned packaging container by means of an ejection stamp.
• a particularly suitable packaging container is specified in claim 19.
• the packaging container contains a bottom with three integrally formed side walls and on the fourth side a side wall part that can be folded down, so that the stack of tape loops can be pushed onto the bottom of the packaging container on this fourth side.
