Abstract
Abstract A mechanism for manipulating cover layers for pressed board in which a carriage is shiftable along a track above a transport path for the layers and entrains a movable support therealong and at least two clamps carried by the support and engageable with opposite edges of the cover layers. The clamps each comprise a fixed jaw, preferably of wood, mounted upon the support and a swingable jaw, preferably also of wood, adapted to engage the cover layers from below and retain them against the respective fixed jaw.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
218 words
A system for the manipulation of a stack of surface-finishing layers applicable to a substrate in the formation of pressed board, comprising: a table receiving said stack with opposite edges thereof overhanging said table; horizontal track means extending from said table to a location horizontally spaced therefrom; a carriage shiftable horizontally along said track means from a position overlying said table to said location; a support vertically displaceable on said carriage; respective clamps on said support along opposite edges thereof, said clamps each having a pair of relatively movable clamp jaws engageable with said overhanging edges of said stack on said table for displacement of said stack to said location, each of said clamps having a fixed jaw on said support and having a movable jaw swingable about a horizontal axis parallel to the overhanging edges of said stack, said fixed jaws lying in a common horizontal plane, a respective axle defining each of said axes and journaled on said support, a first fluid responsive device on said support for rotating each axle, and a second fluid-responsive device on each axle and carrying the respective movable jaw for shifting said movable jaw transversely and relative to the respective axle, said jaws each extending the full length of said stack; and means providing a stack-receiving surface at said location.
