Abstract
Abstract In a laminating machine comprising an applicator roller at a substantially fixed location and a support movable relatively to said roller for an article which is to be laminated with a decorating film that is peeled off a composite web composed of said decorating film on a backing sheet, a feeding device for taking said web to said applicator roller, said feeding device comprising a supply reel for said web, means for axially displacing said supply reel substantially parallel to said applicator roller and a rotatable jockey roller for tensioning said web and disposed between said supply reel and applicator roller, said jockey roller being mounted for substantially vertical displacement as well as pivotal motion about a vertical axis and axial displacement in unison with said supply reel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A feeding apparatus for application of foil in a hot press stamping machine having a hot press stamping roller at a substantially fixed location and carrier means adapted to support an article to be decorated with said foil and which is displaceable with respect to said stamping roller, comprising a supply reel for feeding said foil mounted on a backing sheet, at least one direction changing roller between said supply reel and said stamping roller and over which said foil is passed, a take up reel for receiving and collecting the backing sheet after passing the stamping roller, said supply reel being axially displaceable substantially parallel to said stamping roller, and between said supply reel and stamping roller before application to a face of said article to be decorated, sand foil is led over a jockey roller which is moveable with said supply reel, is displaceable substantially parallel to itself to tension said foil, and is rotatably mounted about an axis extending transversely to its rotary axis in the direction of displacement.
Claim 2
Dependent Claim
172 words
A feeding apparatus for application of foil in a hot press stamping machine having a hot press stamping roller at a substantially fixed location and carrier means adapted to support an article to be decorated with said foil and which is displaceable with respect to said stamping roller, comprising a supply reel for feeding said foil mounted on a backing sheet, at least one direction changing roller between said supply reel and said stamping roller and over which said foil is passed, a take up reel for receiving and collecting the backing sheet after passing the stamping roller, said supply reel being axially displaceable substantially parallel to said stamping roller, and between said supply reel and stamping roller before application to a face of said article to be decorated, sand foil is led over a jockey roller which is moveable with said supply reel, is displaceable substantially parallel to itself to tension said foil, and is rotatably mounted about an axis extending transversely to its rotary axis in the direction of displacement.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 wherein at least one counterweight is connected to said jockey roller to lift the same and set the foil tension.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 1, wherein said jockey roller is adjustable for height and rotatably mounted about a substantially vertical axis, and said foil is passed about the underside of said jockey roller.
Claim 5
Dependent Claim
19 words
Apparatus according to claims 1 and 3, wherein said foil is tensioned under the weight of said jockey roller.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 1, wherein both ends of said jockey roller are mounted in substantially vertical arms of a yoke which is mounted on a vertically movable support for rotation about a vertical axis.
Claim 7
Dependent Claim
58 words
Apparatus according to claim 5, wherein at least one counter weight is connected to said jockey roller yoke near one of its arms by means of an elongated member passing over directional changing rollers, said elongated member serving as a transmission means simultaneously to actuate a second elongated member engaging said yoke near the other of its arms.
Claim 8
Dependent Claim
28 words
Apparatus according to claim 6, wherein said transmission member is a shaft having two sprockets fixed to it about which there pass chains which form said elongate members.
Claim 9
Dependent Claim
65 words
Apparatus according to claim 1, which includes a cross-strut extending over the width of the foil and disposed beneath the foil between the jockey roller and the stamping roller, out of contact with the foil during stamping of the article and elevatable to contact and lift the foil above the upper face of the article during feeding and removal of the article from the apparatus.
Claim 10
Dependent Claim
24 words
Apparatus according to claim 8, wherein said cross-strut is a roller at the end of at least one lever pivotable in a vertical plane.
Claim 11
Dependent Claim
32 words
Apparatus according to claim 1, wherein a stripper is provided upstream of said stamping roller and adapted to be resiliently pressed against the foil for laterally smoothing the same before hot pressing.
Claim 12
Dependent Claim
32 words
Apparatus according to claim 1, wherein displacement of said supply reel and jockey roller is controlled by means of a servo motor responsive to the shape of the article to be decorated.
