Abstract
Abstract A friction roller structure for driving winding-up bobbins at the circumference thereof which includes a roller body normally frictionally coupled by a helical spring to a drive shaft, and means by which the frictional coupling connection between said roller body and said drive shaft may be interrupted by changing the coil diameter of said helical spring.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
180 words
In combination with a drive member formed by a drive shaft, a friction roller structure for selectively establishing and interrupting driving connection between said drive member and a winding-up bobbin of a textile machine, said roller structure including: a rotatable roller member forming a friction roller body supported by and rotatable about the longitudinal axis of said drive shaft, rotatable control means coaxial with and rotatable relative to said drive shaft, coupling means interposed between said friction roller body and said drive shaft and comprising helical spring means having at least a portion thereof arranged within said friction roller body and surrounding an adjacent portion of said drive member formed by said drive shaft, said spring means normally frictionally establishing driving connection between said members, said spring means having one portion rotatably connected to one of said members and having another portion operatively connected to said rotatable control means, said control means being rotatable by said drive member through the intervention of said spring means and also being adapted to be held stationary to interrupt driving connection between said members.
Claim 2
Dependent Claim
180 words
In combination with a drive member formed by a drive shaft, a friction roller structure for selectively establishing and interrupting driving connection between said drive member and a winding-up bobbin of a textile machine, said roller structure including: a rotatable roller member forming a friction roller body supported by and rotatable about the longitudinal axis of said drive shaft, rotatable control means coaxial with and rotatable relative to said drive shaft, coupling means interposed between said friction roller body and said drive shaft and comprising helical spring means having at least a portion thereof arranged within said friction roller body and surrounding an adjacent portion of said drive member formed by said drive shaft, said spring means normally frictionally establishing driving connection between said members, said spring means having one portion rotatably connected to one of said members and having another portion operatively connected to said rotatable control means, said control means being rotatable by said drive member through the intervention of said spring means and also being adapted to be held stationary to interrupt driving connection between said members.
Claim 3
Dependent Claim
64 words
