ABSTRACT:
A machine for automatically tying knots in meat stuffed in a casing by means of a string, comprises an assembly for squeezing the casing over a given extent prior to tying, and a spool unit comprising a spool carrying a supply of string. The spool is rotatably enclosed in a housing which moves only parallel to the axis of feed of the casing. A mechanism having an opening for the passage therethrough of the casing and a hook-shaped member for the passage therethrough of the spool unit, carries elements for temporarily supporting the string over a polygonal path, as well as a relatively axially movable element for detaching the string from the support elements. The use of the mechanism having the hook-shaped component and rotatable to wind the string around the casing, in combination with the spool unit for linearly dispensing the string, permits tying in a spiral direction and also simplifies the design of the machine.
