  • Patent number: 5263627
    Abstract: 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).

  • Patent number: 4484379
    Abstract: 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.

  • Patent number: 4354588
    Abstract: A device for the correct angular positioning of fasteners such as buttons, rivets or the like in the tool of an attachment machine which has a trough-shaped guide rail for these fasteners arranged in front of the tool, the rail having a curved friction lining over at least part of the length of one side thereof and having, on its opposite side, a side wall which is spring-biased in the direction of the friction lining. A swingable slide is associated with this rail and pushes these fasteners forward which are provided with an indexing stop. A finger on the slide touches the indexing stop of the fastener in one position thereof. The pushing surface of the slide is disposed on the longitudinal center line of the feed trough, and the finger is separable from the slide and is arranged laterally of the longitudinal central line.
