Title: Stacker for individual sheets of electrical machines - has sheets guided laterally and braked by roller moving in opposite direction
Inventor: SCHICK WOLFGANG DR ING
IPC: B65H29/22
Filed: 1975-08-22
Abstract: The stacker is for individual sheets or plates of electrical machines e.g. transformers. After cutting from a sheet strip, the individual sheets are transported by a conveying device in the direction of the sheet stack. They are guided laterally by guide strips. Braking of the sheet is by a roller which turns opposite to the sheet direction of motion and lies against the individual sheet. After passing over a stop the roller is pressed against the individual sheet with such a force that the sheet moves against the previous direction of motion and is laid against the stop. During the feed of a further individual sheet, the top sheet is fixed until the further sheet is moved in the opposite direction by the roller.
