DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/DE92/00830 filed Sep. 24, 1992 and based, in turn, on German national application P41 22 473.6 filed Oct. 9, 1991 under the International Convention.
1. Field of the Invention
The invention relates to a method for operating a device for making labels, including looped labels, from strip material, consisting of a dispenser, particularly a rotatably supported roll with strip material or a stacker plate for folded strip material, a feeding device for the strip material wherein the strip end can be inserted and by means of which the inserted strip can be drawn off the dispenser, a gripping device, particularly a gripping clamp for receiving the strip end from the feeding device, a folding device or a folding plate which is transversely slidable with respect to the advance path of the strip and the feeding device and the strip between the jaws of a positioning device, which receive the inserted strip portion transferring it to a storage or processing device, whereby further a separating device for cutting off the strip from the strip material is provided, preferably between the feeding device and the gripping device.
The strip material can be arranged on a dispensing device in the form of a rotatably supported roll. But it is also possible that the strip material folded in zigzag be held in a corresponding stacking device and be removed quasi endlessly therefrom.
By means of the feeding device the strip material is drawn off the dispenser, preferably intermittently. The gripping device can be designed in different ways, but preferably as clamping tongs. The folding device can also be of any design, but consists preferably of a folding plate. "Transversely to the advance path" does not necessarily mean a right angle, but "transverse", can define a right-angle arrangement, as well as an oblique-angle arrangement or an orientation following of an arc of circle. The feeding device can feed the strip linearly, i.e. in a linear path. But it is also possible to make the feeding device so that it revolves around a fixed point of rotation, so that the advance of the strip material takes place along a circular-arc curve.
The separation device for cutting off the strip from the strip material can be arranged at a suitable place. Preferably it is arranged between the feeding device and the gripping device. However other arrangements are also possible.
2. Background of the Invention
An apparatus operating in accordance with the foregoing is described in DE 33 34 646 C2. With the known device it is possible to make U-shaped labels, as well as labels which are folded on top of each other or labels folded in a V-shape from strip segments and to transfer them to corresponding processing stations. The apparatus consists of a feeding device drawing off the strip from a strip roll, a controlled separating device for the strip as well as a subsequently arranged device by means of which the label can be transferred to a piece of fabric, so that the strip can be sewn to the edge (hem) of the piece of fabric in a sewing device.
When the strip is drawn off the roll, by means of a motor-driven or pneumatically movable feeding device, the strip is advanced by a prescribed stretch and is fed to tongs arranged in the path of advance of the strip. The feeding device has two flat rails, running parallel to each other, between which the strip can be inserted. In the rest position of the rails, there is a small distance left between them, so that the strip can be easily inserted. Immediately preceding the front end of the device, considered in the advance direction, a pair of rolls is arranged, which has the purpose to catch the rails as soon as they try to advance, after a short advance stretch and to press them against each other, so that the strip can not slide with respect to the rails. By means of this feeding device the strip is guided towards clamping tongs which grip the strip, whereafter the rails can be retracted. As soon as the rails have returned t
