摘要： A device for separating a topmost workpiece from a stack of textile workpieces, comprises a table support which is guided for upward and downward movement and which is adapted to contain a stack of the workpieces and which is urged in an upward direction by weight means which are engaged with the table. In addition, a holding member is mounted for movement toward and away from the table and includes a lower end which is engageable on the top of the stack to hold the workpieces in position. A strip-off element, for example, a rotatable member having a plurality of radially extending bristles is engageable with the stack adjacent the holding member, and it is rotatable to direct at least the uppermost workpiece over the length of the holding member which is arranged in an inclined position over the stack. The holding member includes holding pins so that as the strip-off member moves upwardly over the holding member, it causes engagement of at least the uppermost workpiece with the pins. The pins are oriented so that the workpieces cannot be removed backwardly in a direction to cause them to fall back into the stack. Since additional workpieces are also likely to be directed up over the holding member, the strip-off member, after it moves to direct at least the uppermost workpiece into engagement with the engagement members along the length of the holding member, then moves in an opposite direction to deflect off any additional workpieces which, by this motion, will become disengaged from the needle and return back to the stack. After the uppermost strip alone is engaged on the holding member, it is raised and positioned in a position to be engaged by a clamping member to move the workpiece into association with an operating machine.
