Abstract:
1. An apparatus for the in particular intermittent feeding of a band-shaped semi-finished material to a press, with two feed elements located opposite each other for the feeding of the band-shaped material in the feeding operation with the clamping of same between the feed elements, with high-lifting means having first drive means coupled with a first of the feed elements for the first of feed elements to be movable from one position, which is closer to a second of the feed elements, into a high-lifted position, which is more remote from the second of the feed elements, in order to enable introduction of the band-shaped material between the feed elements in a non-feeding operation, with band thickness adjusting means having a positioning element coupled with the first of the feed elements for movement between first and second positions, and with locking means by which the positioning element can be locked in a position between the first and second positions, wherein a force of the first drive means is exclusively in the direction towards the high-lifted position of the first of the feed elements, and a resetting movement of the feed elements for adjusting the apparatus to the thickness of the material from the high-lifted position into a band thickness position in which the feed elements lie on the material between the feed elements and, therefore, a positioning of the positioning element in a position corresponding to the band thickness position of the feed element is by resetting forces independent of the force of the first drive means, and wherein the positioning element is guided along a guide and is lockable within this guide by frictional connection with clamping surfaces.
