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.
