A machine (1) for attaching buttons, rivets or the like, preferably to articles of clothing, which buttons, rivets or the like consist of an upper part (124, 125) and a lower part (67, 68) which are fed to an upper tool (9) and lower tool (10) from magazines and are brought into form-locked connection with each other with the interposition of the material (167) by the stroke of a ram (140); in order to optimize the use of different button parts, it is proposed that the upper tool (9) and the lower tool (10) be arranged opposite each other, lying in each case one behind the other in a row on the upper (51) and lower (48) arms of a U-shaped carriage (30) by the positioning of which the upper tool (9), which is to be placed in action in each case, enters into coupling position with respect to the ram (140).

Machine for attaching buttons, rivets or the like, preferably to

A button having a button shank adapted to be fastened to an article of clothing and a section forming a single piece with it which connects via a flexible bridge of material to a button plate. A bridge of material (B) which bears the section (A) and receives the buttoning forces concentrically surrounds the button shank, and the section (A) is developed as a surrounding button edge bead.

Button, particularly for articles of clothing

A clamping buckle for straps, particularly shoulder straps on articles of clothing, with two buckle sections which are swingable with respect to each other around a transverse buckle axis, the buckle sections having a clamping position for clamping the strap. The buckle sections lie one on top of the other approximately parallel to each other with the formation of a gap therebetween. The buckle sections have respective gap sides which face the gap and respective outsides which face away from the gap, and they have slots and bars for diverting the straps including a bar in one buckle section opposite a slot in the other buckle section. The bar of the first buckle section is aligned on its gap side with a plane of the first buckle section and is of at least the same width as the slot of the other buckle section. A loop of the strap wraps around the bar and includes loop end portions passing through the slot that extend by the outside of the second buckle section.
