Abstract

In an apparatus for detaching an article from a member attached thereto, the attached article and member are supported on a grid such that the member is in contact with a substantially rigid surface of the grid and the article is suspended away from the rigid surface. Holders hold the member to the rigid surface. While the member is held to the rigid surface, a punch detaches the article and the member. The member from which the article has been detached is gripped by a pin assembly and the gripped member is removed from the substantially rigid surface by raising the pin assembly.
