Abstract
High speed, extremely accurate web or sheet-fed segment die cutting or lamination apparatus ( ) has a processing station ( ), which receives a sheet or web segment, and is provided with a vacuum hold-down plate ( ) for holding initially fed segments ( ). The plate is shiftable as necessary along orthogonal X-Y axes in the plane of the segment ( ), and/or is rotatable about a &thgr; axis transverse to the segment plane. Plate movement is effected by a series of aligned, translatable eccentric drive units ( ). Segments ( ) carry positioning fiducials ( ) that are compared with fixed reference indicia ( ) in the station ( ). The comparison data is used by a controller ( ) to generate the plate movement information used in simultaneous operation of the associated plate drive units ( ).
