Title: Feed unit for handling magazine supplied sheets or plates
Inventor: PERBERSCHLAGER ALOIS
IPC: B65H5/24
Filed: 1994-01-31
Granted: 1998-05-07
Abstract: Stacked plates (2) are extracted from a magazine stack (6) and are fed along a linear track to a station (4) where a foil (1) is fed from a spool and is bonded to the surface. After bonding the foil is cut by a rotary unit (10) the sheets are transferred from the stack under the control of a mechanical unit with actuation signals generated by a computer (C1). The unit has a clutched stop-go action to control the overlap of plates as they pass along the track. The feed rate is controlled by the computer. The speed of a drive roller may be varied to accelerate the products. A second computer (C2) controls the foil bonding and cutting station.
