Sheet feeder having adaptive mechanism for assuring dependable automatic operation when the stack of sheets to be fed consists of sheets having varying thicknesses and weights. In a sheet feeder having pickers (102) to move a document from the top of a stack of sheets supported by a moveable table (10) to a feedin position, the latter possibly including a vacuum belt (106) for moving the document, sensors (132, 134) supply signals to indicate a sheet has been picked. After moving the pickers and table to initial positions, the controller (150) moves the picker to a predetermined reference position. If a sheet is picked above or below the predetermined initial position, the position of the table is adjusted accordingly. In a second embodiment in a recirculating automatic sheet feeder, the table is initially positioned then after feeding the sheets from the stack once, it is initialized at a second predetermined position depending on the number of documents in the stack and on the position of the table prior to picking the documents a second time.

A method for manufacturing plywood includes receiving a face sheet on a main conveyor and feeding a plurality of pieces of core veneer onto a veneer conveyor by an automated core veneer feeder. The method also includes removing one or more of the plurality of pieces of core veneer from the veneer conveyor and placing the one or more of the plurality of pieces of core veneer onto the face sheet.
摘要:
A device for positioning interlayers, comprising: gripping means (2), predisposed to grip an interlayer (L) at an end zone of the interlayer (L) itself, which are mobile between a first position, at which they can grip an interlayer (L) on an upper lying plane (G1), and a second position, at which they can release the interlayer (L) onto a lower lying plane (G2); the gripping means (2) are mobile between the first and the second position in rotation about a horizontal axis of rotation (Y) and in translation along a horizontal direction of transport (X) perpendicular to the axis of rotation (Y).
