Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
In a device for placing a ring-shaped band on a ball of yarn or the like wherein the band is placed on the ball by means of a first and a second band carrier mounted on a support which is displaceable with respect to the ball, the ball being held between the band carriers, the improvement comprising a guiding slideway on said support, means slidably supporting said first band carrier in said slideway, means rigidly attaching said second band carrier to said support, biasing means normally urging said first band carrier away from said second band carrier, power drive means reciprocating said first band carrier in said slideway relative to said second band carrier, and control means for said power drive means for moving said first band carrier towards said second band carrier during application of the band on said band carriers and after placing the band onto the ball, to thereby grip said ball, by displacement of said support carrying said band carriers, the ball being held between said band carriers during displacement of the support.
Claim 2
Dependent Claim

In a device for placing a ring-shaped band on a ball of yarn or the like wherein the band is placed on the ball by means of a first and a second band carrier mounted on a support which is displaceable with respect to the ball, the ball being held between the band carriers, the improvement comprising a guiding slideway on said support, means slidably supporting said first band carrier in said slideway, means rigidly attaching said second band carrier to said support, biasing means normally urging said first band carrier away from said second band carrier, power drive means reciprocating said first band carrier in said slideway relative to said second band carrier, and control means for said power drive means for moving said first band carrier towards said second band carrier during application of the band on said band carriers and after placing the band onto the ball, to thereby grip said ball, by displacement of said support carrying said band carriers, the ball being held between said band carriers during displacement of the support.
Claim 3
Dependent Claim
45 words
The improvement of claim 1 wherein said band carrier support is displaceable in a first direction for pushing a band onto the ball, and is displaceable in an opposite direction for withdrawing the ball from a winding mandrel with the ball held between said carriers.
Claim 4
Dependent Claim
13 words
The improvement of claim 1 wherein the band carriers are provided with barbs.
Claim 5
Dependent Claim
16 words
The improvement of claim 1 wherein said power drive means is a fluid operated piston-cylinder assembly.
Claim 6
Dependent Claim
20 words
The improvement of claim 4 wherein said piston-cylinder assembly comprises a pneumatic cylinder including a return spring for the piston.
Claim 7
Dependent Claim
25 words
The improvement of claim 1 wherein a shaping ring is coordinated with the band carriers for preforming the ball prior to placing the band thereon.
Claim 8
Dependent Claim
24 words
The improvement of claim 1 wherein said shaping ring is mounted on an arm extending from said band carrier support between said band carriers.
