Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
281 words
A device for automatically transferring a double-coated adhesive transfer tape of the type having adhesive substance to be transferred coated on a release material in a discontinuous manner such that portions of the adhesive substance are separated by small intermediate spaces in the longitudinal direction, and longitudinal edge portions of the release material are not coated with the adhesive substance, leaving portions of the release material exposed on upper and lower sides of the release material, said device comprising: a substantially hollow casing; means for rotatably supporting a roll of double-coated adhesive transfer tape, said support means located inside said casing; a resilient pressure plate for contacting the roll of tape for hindering the free rotation thereof, said pressure plate having first and second ends, said first end attached to said casing, and said second end of said pressure plate having means for contacting only the longitudinal edge portions of the release material not coated with the adhesive substance; an opening in a lower part of said casing for exposing at least the patches of adhesive substance on the roll of tape rotatably supported on said support means outwardly of said casing for transferring the adhesive substance to a substrate; an outlet in said casing for discharging the release material from which the adhesive substance has been transferred to a substrate; a guide piece provided on said casing having a groove or slot directed toward the tape roll; and a free contact piece slidably received in said groove or slot of said guide piece, said free contact piece contacting the tape roll for preventing slack in the release material of the transfer tape from which the adhesive substance has been transferred.

A device for automatically transferring a double-coated adhesive transfer tape of the type having adhesive substance to be transferred coated on a release material in a discontinuous manner such that portions of the adhesive substance are separated by small intermediate spaces in the longitudinal direction, and longitudinal edge portions of the release material are not coated with the adhesive substance, leaving portions of the release material exposed on upper and lower sides of the release material, said device comprising: a substantially hollow casing; means for rotatably supporting a roll of double-coated adhesive transfer tape, said support means located inside said casing; a resilient pressure plate for contacting the roll of tape for hindering the free rotation thereof, said pressure plate having first and second ends, said first end attached to said casing, and said second end of said pressure plate having means for contacting only the longitudinal edge portions of the release material not coated with the adhesive substance; an opening in a lower part of said casing for exposing at least the patches of adhesive substance on the roll of tape rotatably supported on said support means outwardly of said casing for transferring the adhesive substance to a substrate; an outlet in said casing for discharging the release material from which the adhesive substance has been transferred to a substrate; a guide piece provided on said casing having a groove or slot directed toward the tape roll; and a free contact piece slidably received in said groove or slot of said guide piece, said free contact piece contacting the tape roll for preventing slack in the release material of the transfer tape from which the adhesive substance has been transferred.
Claim 3
Dependent Claim
36 words
A device as in claim 1, wherein said outlet in said casing for discharging the release material has means for contacting only the longitudinal edge portions of the release material not coated with the adhesive substance.
Claim 4
Dependent Claim
43 words
A device as in claim 1, wherein said guide piece is provided on an upper forward portion of said casing, and a finger placing plate having at least two protuberances or indentations is provided on said casing rearwardly and below said guide piece.
Claim 5
Dependent Claim
41 words
A device as in claim 1, wherein said guide piece has a protuberance for slidably retaining said free contact piece within said groove or slot of said guide piece when no roll of tape is rotatably supported on said support means.
Claim 6
Dependent Claim
20 words
A device as in claim 1, wherein said casing has an opening for hanging said device when not in use.
