Abstract
Abstract Apparatus for pivoting a tensioned web of material away from an adhesive applicator roller therefor comprises a guide roller for the web carried by first pivotal levers and a web tensioning bar extending parallel to the guide roller and carried by second pivotal levers so as to keep the web under tension when the first pivotal levers are swung to move the web past over the guide roller away from the applicator roller. Means are provided which are operative on pivoting of the first levers and which utilize the pivoting motion thereof for controlling pivoting movement of said second levers required to maintain or increase the tension in the web.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
Apparatus for pivoting a tensioned web of material away from an adhesive applicator roller therefor comprising in combination, first pivotal levers, a guide roller for the web mounted on said first pivotal levers, said guide roller being movable by said first pivotal levers between a first position for holding the web against the adhesive applicator roller and a second position for permitting the web to move away from the adhesive applicator roller, second pivotal levers, a web tensioning bar extending parallel to said guide roller mounted on said second pivotal levers, means for pivotally moving said second levers in response to the pivotal movement of said first levers to position said web tensioning bar in an inoperative position out of engagement with the web in the first position of said guide roller and in an operative position in tensioning engagemment with the web in the second position of said guide roller with the web away from the adhesive applicator roller.
Claim 2
Dependent Claim
160 words
Apparatus for pivoting a tensioned web of material away from an adhesive applicator roller therefor comprising in combination, first pivotal levers, a guide roller for the web mounted on said first pivotal levers, said guide roller being movable by said first pivotal levers between a first position for holding the web against the adhesive applicator roller and a second position for permitting the web to move away from the adhesive applicator roller, second pivotal levers, a web tensioning bar extending parallel to said guide roller mounted on said second pivotal levers, means for pivotally moving said second levers in response to the pivotal movement of said first levers to position said web tensioning bar in an inoperative position out of engagement with the web in the first position of said guide roller and in an operative position in tensioning engagemment with the web in the second position of said guide roller with the web away from the adhesive applicator roller.
Claim 3
Dependent Claim
87 words
Apparatus according to claim 1 wherein said means for pivotally moving said second pivotal levers comprise means for operatively coupling said first pivotal levers to said second pivotal levers, said coupling means being arranged to move said web tensioning bar in the same direction as said guide roller during the movement of said guide roller from said first position to said second position with said web tensioning bar moving from said inoperative position behind said guide roller to said operative position in front of said guide roller.
Claim 4
Dependent Claim
49 words
Apparatus according to claim 2 wherein the pivot axis of said first levers is spaced from the pivot axis of said second levers and wherein said coupling means comprise slots in said first levers and cam means on said second levers displaceable within said slots in said first levers.
