Abstract
Abstract The invention relates to a thread-tensioning and balloon control or breaking motion for unwinding yarn from crosswound or other supply packages on textile machines, particularly on weaving machines. A circular, supporting, rimlike means is provided to be positioned coaxially to and adjacent the package unwinding end, and stands approximately normal to the package axis. It is provided internally with a plurality of pivoted, spring loaded tensioning members. These are spaced circumferentially of the supporting rimlike means and lie tangentially on the outer surface of the package to restrain and inhibit the ballooning tendencies of the yarn being drawn from the package.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A thread-tensioning and balloon control motion for the unwinding of yarn from supply packages on textile machines, particularly on weaving machines, characterized in that, a rimlike supporting means is provided on a holding arm, said supporting means surrounding the supply package adjacent its unwinding end and standing at least approximately normal and coaxial to the package axis, pivot pins spaced about the supporting means and holders pivoted on said pins, at least one springlike tensioning member fixed in each said holder and so arranged at spaced intervals circumferentially of the rimlike supporting means that they lie tangentially against the outer surface of the supply package, and resilient means connected to one end of each holder and to an anchor means on a part of the rimlike supporting means for urging the tensioning members against the surface of the package.
Claim 2
Dependent Claim
139 words
A thread-tensioning and balloon control motion for the unwinding of yarn from supply packages on textile machines, particularly on weaving machines, characterized in that, a rimlike supporting means is provided on a holding arm, said supporting means surrounding the supply package adjacent its unwinding end and standing at least approximately normal and coaxial to the package axis, pivot pins spaced about the supporting means and holders pivoted on said pins, at least one springlike tensioning member fixed in each said holder and so arranged at spaced intervals circumferentially of the rimlike supporting means that they lie tangentially against the outer surface of the supply package, and resilient means connected to one end of each holder and to an anchor means on a part of the rimlike supporting means for urging the tensioning members against the surface of the package.
Claim 3
Dependent Claim
46 words
A thread-tensioning and balloon control motion as defined in claim 1, characterized in that, said resilient means comprises tension springs which act on the tensioning members through their holders, and a common adjusting device arranged in the rimlike supporting means for simultaneous adjustment of said springs.
Claim 4
Dependent Claim
46 words
A thread-tensioning and balloon control motion according to claim 1, including means in the rimlike supporting means for simultaneously pivoting said tensioning members from their operating position to an ineffective position wherein the tensioning members are withdrawn and lifted off the surface of the supply package.
Claim 5
Dependent Claim
57 words
A thread-tensioning and balloon control motion as defined in claim 1, characterized in that, a pivot pin is provided for interconnecting said rimlike support means to the holding arm so that the support means can be swung about the pivot pin out of its operating position into a position in which a supply package can be exchanged.
