ABSTRACT:
The invention relates to convoluting a doubled, unknotted length of thread about a clip which is closed about the gathered mouth of a tubular wrapper such as a sausage casing to form a loop by which the sausage can be hung. The clip secures the loop to the casing and the weight of the sausage merely makes a tighter grip. An apparatus to produce the loop secured to the clip and casing comprises a punch, a clip guide having opposite grooves for guiding the clip legs, a die for receiving each clip and for cooperating with the punch to close the clip around the gathered mouth end of the wrapper, a thread-withdrawing device disposed beside the clip feed path, a thread snubber and a looping hook, a winding head which is axially displaceable into the feed path for the clip, the winding head being provided with a groove in its end face and a thread-receiving recess transverse to the axis of the winding head and somewhat set back from its end face, part of the groove and the thread-receiving recess defining a hook, and means for rotating the winding head so as to form an eyelet in the thread independent of the loop, advance of the clip causing one of the clip legs to enter the eyelet and the clip thereafter closing.
