Abstract
Abstract A compact and inexpensive decorator for transferring labels by heat and pressure from a carrier strip to articles such as bottles. The decorator is designed as a unit, including infeed and outfeed conveyors, a turret for holding articles during labelling and maintaining their shape by inflation, a deck bearing a transport for the carrier web and a device for impressing labels from the strip onto the articles, and a control module. For round articles the turret includes interchangeable Index and Decorator cups, while for oval articles an easily removed turret base with article cutouts is used. The deck may be adjusted in its height and angular orientation with respect to the turret to permit decoration of a wide variety of article faces. The carrier web transport includes a capstan web drive for pulling the web, a double gate, and a dancer roll, which provide label-by-label advance of the web controlled by signals from a photoelectric web monitor and a container detector. The double gate and dancer roll are included to avoid regions of slack or high tension in the web during intermittent advance.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
262 words
In a device for transferring labels from a carrier web to articles comprising a turret for rotating the articles past a site of label transfer and a carrier web transport for directing the carrier web along a prescribed route at a desired speed, which prescribed route includes the site of label transfer, an improved carrier web transport comprising: web dispensing and collecting means; a capstan web drive near the web collecting means for pulling the carrier web through the prescribed route during a period of label transfer, which capstan web drive exerts no pull on the web during interim periods between the periods of label transfer; a dancer roll which is movable in a slot and is subjected to a force toward one end of the slot, which force is less than the pull exerted in the opposite direction by the capstan web drive during periods of label transfer; and a double gate at the other end of said slot including first and second jaws which alternately clamp the carrier web, the first jaw only during periods of label transfer and the second jaw only during interim periods; wherein said prescribed route comprises respectively the web dispensing means, the first jaw, the dancer roll, the second jaw, the site of label transfer, the capstan web drive, and the web collecting means; whereby the double gate and dancer roll collect a carrier web surplus from said web dispensing means during interim periods and release this surplus past the labelling site under the influence of the capstan web drive during periods of label transfer.
Claim 2
Dependent Claim
262 words
In a device for transferring labels from a carrier web to articles comprising a turret for rotating the articles past a site of label transfer and a carrier web transport for directing the carrier web along a prescribed route at a desired speed, which prescribed route includes the site of label transfer, an improved carrier web transport comprising: web dispensing and collecting means; a capstan web drive near the web collecting means for pulling the carrier web through the prescribed route during a period of label transfer, which capstan web drive exerts no pull on the web during interim periods between the periods of label transfer; a dancer roll which is movable in a slot and is subjected to a force toward one end of the slot, which force is less than the pull exerted in the opposite direction by the capstan web drive during periods of label transfer; and a double gate at the other end of said slot including first and second jaws which alternately clamp the carrier web, the first jaw only during periods of label transfer and the second jaw only during interim periods; wherein said prescribed route comprises respectively the web dispensing means, the first jaw, the dancer roll, the second jaw, the site of label transfer, the capstan web drive, and the web collecting means; whereby the double gate and dancer roll collect a carrier web surplus from said web dispensing means during interim periods and release this surplus past the labelling site under the influence of the capstan web drive during periods of label transfer.
Claim 3
Dependent Claim
38 words
The device for transferring labels of claim 1 further comprising article monitoring means in said turret for activating the capstan web drive and opening the second jaw when said article monitoring means detects an article to be labelled.
Claim 4
Dependent Claim
35 words
The device for transferring labels of claim 1 further comprising web monitoring means for deactivating the capstan web drive and closing the second jaw when said web monitoring means detects an index of web advance.
Claim 5
Dependent Claim
37 words
The device for transferring labels of claim 3 wherein said web monitoring means comprises a photoelectric detector which is trained on the label-bearing portion of the carrier web and detects the presence or absence of a label.
Claim 6
Dependent Claim
48 words
The device for transferring labels of claim 1 wherein said double gate comprises a reciprocating air cylinder with first and second positions, wherein the first position closes the first jaw and opens the second jaw, while the second position closes the second jaw and opens the first jaw.
