Abstract
Abstract A method of and an apparatus for cutting labels of heat-shrinkable tube covering bottles in intimate contact with the outer periphery of the bottle by melting the label with hot air applied thereto. The hot air is applied by a jet nozzle comprising a plurality of blocks which are adjustingly movable toward or away the label on the bottle. For use with bottles having a trunk of curved configuration, the blocks are individually adjusted to position each block at a specified distance from the curved bottle surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
109 words
A method of cutting a label from a heat-shrinkable tube covering the outer periphery of a bottle in intimate contact therewith by melting the label by the application of hot air thereto, wherein a plurality of blocks are superposed along the axial direction of the bottle and in opposition to the label and are each individually adjustingly moved toward or away from the label to position a label-facing side of each block at a predetermined distance from the surface of the label, and wherein the hot air is discharged from the label-facing side of each block to cut the label over the entire length thereof in the axial direction.
Claim 2
Independent Claim
109 words
A method of cutting a label from a heat-shrinkable tube covering the outer periphery of a bottle in intimate contact therewith by melting the label by the application of hot air thereto, wherein a plurality of blocks are superposed along the axial direction of the bottle and in opposition to the label and are each individually adjustingly moved toward or away from the label to position a label-facing side of each block at a predetermined distance from the surface of the label, and wherein the hot air is discharged from the label-facing side of each block to cut the label over the entire length thereof in the axial direction.
Claim 3
Dependent Claim
50 words
A method of cutting a label as defined in claim 1, wherein compressed air is forced in between the label and the bottle from an axial end of the label at the cutting position to diminish the intimate contact of the label with the bottle, when the label is cut.
Claim 4
Dependent Claim
38 words
A method of cutting a label as defined in claim 1 wherein the hot air is discharged from a slitlike orifice formed in the label-facing side of each block and extending in the axial direction of the bottle.
Claim 5
Dependent Claim
46 words
A method of cutting a label as defined in claim 1, wherein the hot air is discharged from an orifice comprising a plurality of small circular or elliptical holes formed in the label-facing side of each block and arranged in the axial direction of the bottle.
Claim 6
Dependent Claim
53 words
A method of cutting a label as defined in claim 1, wherein the hot air is discharged at a temperature of at least 150° C. at a velocity of 30 m/sec to 250 m/sec, the distance between the label-facing side of each block and the label surface being 0.5 mm to 15 mm.
Claim 7
Dependent Claim
24 words
A method of cutting a label as defined in claim 3, wherein the slit-like orifice has a width of 0.1 mm to 2.0 mm.
Claim 8
Independent Claim
96 words
An apparatus for cutting a label from a heat-shrinkable tube covering the outer periphery of a bottle in intimate contact therewith by melting, comprising a plurality of blocks positionable in opposed relation to a surface of the label and superposed along the axial direction of the bottle, each of the blocks being movable toward or away from the label to position a label-facing side of the block at an adjustable distance from the surface of the label, each block being formed in its label-facing side with an orifice for discharging hot air against the label surface.
Claim 9
Independent Claim
96 words
An apparatus for cutting a label from a heat-shrinkable tube covering the outer periphery of a bottle in intimate contact therewith by melting, comprising a plurality of blocks positionable in opposed relation to a surface of the label and superposed along the axial direction of the bottle, each of the blocks being movable toward or away from the label to position a label-facing side of the block at an adjustable distance from the surface of the label, each block being formed in its label-facing side with an orifice for discharging hot air against the label surface.
Claim 10
Dependent Claim
29 words
An apparatus for cutting a label as defined in claim 7, wherein the blocks are accommodated in a nozzle box and adjustingly movable toward or away from the label.
Claim 11
Dependent Claim
29 words
An apparatus for cutting a label as defined in claim 7, wherein each orifice is in the form of a slit extending along the axial direction of the bottle.
Claim 12
Dependent Claim
28 words
An apparatus for cutting a label as defined in claim 7, wherein the orifice comprises small circular or elliptical holes arranged in the axial direction of the bottle.
Claim 13
Dependent Claim
50 words
An apparatus for cutting a label as defined in claim 8, wherein each of the blocks is biased toward the bottle by a spring provided within the nozzle box and is fixed to the nozzle box against the force of the spring by fastening means provided on the nozzle box.
Claim 14
Dependent Claim
42 words
An apparatus for cutting a label as defined in claim 8 characterized in that the nozzle box has inside, wherein a hot air holding space, to which hot air is supplied, is provided within the nozzle box in communication with the orifice.
Claim 15
Dependent Claim
32 words
An apparatus for cutting a label as defined in claim 7, wherein a nozzle for forcing compressed air in between the label and the bottle is provided above and/or below the blocks.
Claim 16
Dependent Claim
23 words
An apparatus for cutting a label as defined in claim 9, wherein the slit has a width of 0.1 mm to 2.0 mm.
