Positioning device for button setting machines.

摘要

A positioning device (10) comprises a reciprocally movable support table (14) having a surface (14a) extending in a plane above a clinching die (12) of a button setting machine (11) for supporting a garment fabric to which a button (A) is attached, and a pair of guide mambers (15, 16) disposed on the surface (14a) in perpendicular relation. The table (14) includes a recess (22) which is registered with the clinching die (12) when the table is in an advanced position. One of the guide member (15) is positionally adjustable in a direction perpendicular to the direction of movement of the table (14) and the other guide member (16) is positionally adjustable in a direction parallel to the direction of movement of the table (14). Thus the garment fabric can be positioned accurately and easily with respect to the clinching die (12) by simply putting two adjacent edges of the garment fabric into guided engagement with the respective guide members (15, 16). The positioning device may includes a stopper mechanism (35) for limiting reciprocation of the table (14) at the advanced position and a retracted position remote from the clinching die (12).
