Abstract
A machine for separating single plies of fabric from a stack of fabric plies uses a roller provided with a fabric ply engaging mechanism. The roller engages the top ply of fabric and removes it with a rolling action. The engaging mechanism comprises a pivotable rod mounted on the roller and provided with protruding pins which engage the top ply of fabric from the stack as the rod is pivoted. The machine can be arranged to sort alternate plies of fabric from one stack into separate stacks. The machine can be provided with an adjustable support for holding the stack and with a detector for detecting the presence of a single fabric ply on the roller. The engaging mechanism is provided with a pair of pin holders whose spacing can be varied, the roller is provided with a plurality of rows of air holes to provide air flow to aid in separating a single ply from the stack, a detection arrangement is included which can detect folds in the single ply during its transport on the roller, and the adjustable support uses an improved arrangement for maintaining an essentially constant upward pressure by the stack against the roller during pickup despite changes in the size of stack as it is depleted by removal of the plies.
