Abstract
Abstract A false twisting machine for textile yarn has a thread supply rack and a thread wind-up mechanism which are located on the base of the machine. These components, as well as the false-twisting device and the various thread draw roller mechanisms are all accessible from the base of the machine via a corridor formed between the various components. The machine also has heaters which are located above the other components and may be accessible by a separate service platform located at a higher level. Two machines may be mounted adjacent one another in a mirror symmetry.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A false twisting machine for textile fibers, including a base, a frame and a set of components comprising: a supply bobbin rack, mounted on said base; wind up spool means, located on said base adjacent to said supply bobbin rack; first draw roller means, located on said frame above said wind up spool means, for pulling thread from the bobbins on said supply bobbin rack; first heater means, located above said first draw roller means; false twisting means, located on said frame below said first heater means, and defining a thread cooling zone therewith; second draw roller means, located on said frame below said false twisting means, for pulling thread through said first heater means and through said false twisting means; second heater means, located above said first draw roller means and adjacent said first heater means; and third draw roller means, located on said frame above said wind-up spool means, for pulling thread through said second heater means and for guiding it to said windup spool means.
