Abstract
A hand operated device for transferring an adhesive film from a carrier tape to a substrate is provided with a single spool having a portion containing the roll of carrier tape and a large diameter portion having a plurality of knurls formed on the circumference thereof. The tape is fed from the spool to contact the substrate and then fed between the knurls. A spring arm serves as a clutch by maintaining the tape in contact with the knurls but allowing slippage of the tape therebetween at a predetermined tape tension.
Claims15
A hand operated device for transferring a film from a carrier tape to a substrate comprising:
- wall structure forming a housing having an applicator means and a single spool mounted for rotation within said housing;
- said spool having a portion carrying a roll of carrier tape and being supported for feeding the carrier tape over said applicator means;
- a portion of said spool adjacent said roll carrying portion having an outer perimeter disposed for receiving said carrier tape after its passage over said applicator means;
- and
- spring means forcing said carrier tape against said spool outer perimeter for driving said carrier tape after its passage over said applicator means and allowing slippage therebetween to prevent breakage of said carrier tape.
A method of transferring a film from a carrier tape to a substrate including the steps of:
- providing a housing having a single spool comprising a portion containing a roll of carrier tape and a portion adjacent said roll containing portion having an outer perimeter, and an applicator means for contacting the substrate;
- feeding said carrier tape from said single spool containing portion over said applicator means and over the periphery of said single spool outer perimeter;
- and
- providing pressure to said carrier tape at the area of contact with said spool outer periphery of sufficient force to cause friction between said spool outer periphery and said carrier tape to feed said carrier tape, and to allow slippage between said spool outer periphery and said carrier tape when said carrier tape is subjected to a predetermined tensile force.
