Abstract
Abstract A method and apparatus for loading forming dies with a mold blanket which comprises providing a lay-up station with simulated die forms outside the forming dies where the mold blanket material may be distributed as it will be in the die and providing a pick-up assembly composed of a plurality of pins distributed around the blanket which pins are pressed in to perforate the blanket and certain of the pins are moved transversely to others to tension the blanket whereby the blanket may be lifted bodily, moved into a die press, and dropped on to the forming dies prior to the pressing cycle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
A device for moving a sheet of penetrable flacid material from a lay-up position to a position on a mold which comprises: (a) a frame, (b) a plurality of horizontally spaced support means each mounted on said frame for vertical adjustment relative to a horizontal plane, (c) a plurality of straight, smooth pins all mounted vertically on said respective support means in parallel relation to each other, (d) means for moving said frame and support means vertically in a direction parallel to said respective pins into a position penetrating a sheet to be moved, (e) means for shifting a plurality of said pins angularly relative to others of said pins; (f) and means to shift said frame laterally from a pick-up position to loading position over a mold, said rods being vertically adjustable so they may be readily adapted to varying mold contours.
Claim 2
Independent Claim
143 words
A device for moving a sheet of penetrable flacid material from a lay-up position to a position on a mold which comprises: (a) a frame, (b) a plurality of horizontally spaced support means each mounted on said frame for vertical adjustment relative to a horizontal plane, (c) a plurality of straight, smooth pins all mounted vertically on said respective support means in parallel relation to each other, (d) means for moving said frame and support means vertically in a direction parallel to said respective pins into a position penetrating a sheet to be moved, (e) means for shifting a plurality of said pins angularly relative to others of said pins; (f) and means to shift said frame laterally from a pick-up position to loading position over a mold, said rods being vertically adjustable so they may be readily adapted to varying mold contours.
Claim 3
Independent Claim
258 words
A device for moving a sheet of penetrable flacid material from a lay-up position to a position on a mold which comprises: (a) a frame, (b) a plurality of horizontally spaced support means each mounted on said frame for vertical adjustment relative to a horizontal plane, (c) a plurality of straight, smooth pins all mounted vertically on said respective support means in parallel relation to each other, (d) means for moving said frame and support means vertically in a direction parallel to said respective pins into a position penetrating a sheet to be moved, (e) means for shifting a plurality of said pins relative to others of said pins in a direction transverse to the axis of said pins, and (f) means to shift said frame laterally from a pick-up position to a loading position over a mold, said support means including a mounting block, means to mount one or more pins on said mounting block, a slide block on and underneath said mounting block, means to mount one or more pins on said slide block in substantially parallel relation to the pins on said mounting block, and means to move said slide block relative to said mounting block to cause said pins to move transversely relative to each other, while maintaining their parallel relationship, said slide block having mounted thereon two pins having portions mounted to overlie the sides of the mounting block and having a sliding relation with respect to said mounting block to guide the slide block in its motion relative to the mounting block.
