Abstract

Abstract In a label overprinter or an overprinting applicator an arrangement for driving a label web (16) includes a roller (10) with a high friction surface and a substantial wrap-round of the web, and a rewind reel carrying a dancer roll (18) on an arm (22) which roll applies a tension to the web. A web reel mounting includes resilient fingers (84) supported around a shaft (80) and a frustoconical member (92) operative axially to expand the fingers (84) to engage the internal periphery of a reel.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 122 words
An arrangement for driving intermittently a label web or other elongate member along a path comprising an intermittently-driven roller (10) with a peripheral high friction surface, means (12, 14) for guiding the web so that it contacts the peripheral high friction surface over a major proportion of the periphery, and a rewind reel mounting (26) downstream along the web path from said roller (10) characterized by a dancer roll (18) mounted on an elongate member (22) pivotal about the axis of rotation (24) of the rewind reel (26) and biasing means (28) providing a biasing force at the dancer roll (18) whereby to impart tension in the web over its path between the high friction roller (10) and the rewind reel (26).
Claim 2
Dependent Claim 122 words
An arrangement for driving intermittently a label web or other elongate member along a path comprising an intermittently-driven roller (10) with a peripheral high friction surface, means (12, 14) for guiding the web so that it contacts the peripheral high friction surface over a major proportion of the periphery, and a rewind reel mounting (26) downstream along the web path from said roller (10) characterized by a dancer roll (18) mounted on an elongate member (22) pivotal about the axis of rotation (24) of the rewind reel (26) and biasing means (28) providing a biasing force at the dancer roll (18) whereby to impart tension in the web over its path between the high friction roller (10) and the rewind reel (26).
Claim 3
Dependent Claim 26 words
An. arrangement according to claim 1 characterised in that guide means comprise two guide rollers (12,14) placed adjacent to but spaced from the high friction roller.
Claim 4
Dependent Claim 26 words
An arrangement according to claim 1 characterized in the web path encompasses an arc of at least 270 of the periphery of the high friction roller.
Claim 5
Dependent Claim 57 words
A web reel mounting device comprising a shaft (80) mounting fingers (84) extending substantially parallel to but inwardly towards the shaft, characterized in that each finger mounted to the shaft, each finger being resiliently deflectable relative to the shaft, and a member (88) manually operative to deflect simultaneously the fingers outwardly to parallel relationships to the shaft.
Claim 6
Dependent Claim 57 words
A web reel mounting device comprising a shaft (80) mounting fingers (84) extending substantially parallel to but inwardly towards the shaft, characterized in that each finger mounted to the shaft, each finger being resiliently deflectable relative to the shaft, and a member (88) manually operative to deflect simultaneously the fingers outwardly to parallel relationships to the shaft.
Claim 7
Dependent Claim 30 words
A device according to claim 4, characterised in that the resilience of each finger is provided by a portion (86) of reduced cross-secticnadjacent to the mounting point to the shaft.
Claim 8
Dependent Claim 26 words
A device according to claim 4 or claim 5 characterised in that the fingers are mounted to the shaft through the intermediary of a hub (82).
Claim 9
Dependent Claim 97 words
A device according to claim 4, 5, 6 characterised in that deflecting member (88) comprises a sleeve with a first cylindrical portion (90) of smaller diameter, a frusto-conical portion (92) and a second cylindrical portion (93) of large diameter, the sleeve being slidable within limits axially of the shaft so that with the sleeve at an inner limit position the fingers (84) are deflected inwardly towards the shaft and at an outer limit position the second cylindrical portion supports the free ends of the fingers so that the latter are in said parallel relationship with the shaft.
