Automatic transferring device for double-coated adhesive tape

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.
