Abstract
In a button-holder for a button-sewing machine, two clamp parts (8,9) for the button (7) are guided in a parallel guide holder (28) so as to be movable by a pneumatic cylinder (34) in opposite directions. The parallel guide holder (28) is swingable horizontally by a pneumatic cylinder (17) to displace the clamp parts (8,9) from a sewing position (A) to a resting position (B). Thus, the button-holder does not require adjustment for different sized buttons and the button can be inserted away from the sewing region.
