ABSTRACT:
Apparatus for depositing a stack of flexible articles, includes stack deposit means (12) for contacting the stack and placing it with respect to a reference point. The stack deposit means has at least one surface means (30) for contacting the top or bottom of the stack. Means (15) is provided to withdraw the at least one surface means in a direction substantially parallel to the top or bottom of the stack, respectively. The at least one surface means is arranged so that any surface (31) thereof in contact with the top or bottom of the stack, respectively, moves at a relative speed along the top or bottom of the stack sufficiently less than the speed of withdrawal of the surface means to substantially prevent rolling of the articles of the stack during withdrawal.
