Abstract

A hand operated device for transferring an adhesive film from a carrier tape to a substrate is provided with a feed spool containing the carrier tape, and a take-up spool mounted in a housing. The carrier tape is fed from the feed spool to the take-up spool over an applicator bar and the take-up spool is driven by the feed spool through a clutch plate to maintain a degree of tension in the carrier tape during operation of the device.

Claims

1. 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 containing a carrier tape disposed on a feed spool axially mounted for rotation and having a face surface;

a take-up spool rotatably mounted for receiving tape from said feed spool after having passed over said applicator means,

a clutch plate having a face surface controlling said feed spool face surface and disposed for rotation about a common axis with said feed spool, said clutch plate face surface contacting said take-up spool face surface for rotating said take-up spool upon rotation of said clutch plate; and

biasing means for forcing said face surface of said clutch plate into contact with said face surface of said feed spool;

whereby tape moved over said applicator means is effective to cause rotation of said feed spool and said clutch plate through frictional contact therebetween to thereby rotate said take-up spool, and a predetermined tensile force in said tape is effective to cause slippage between said feed spool and said clutch plate.

2. A device as set forth in claim 1 wherein said take-up spool is provided with a plurality of gear teeth disposed about the periphery thereof and said clutch plate is provided with a plurality of gear teeth disposed about the periphery thereof and said contact between said clutch plate and said take-up spool occurs through meshing of said gear teeth.

3. A device as set forth in claim 1 wherein one of said face surfaces comprises a ring of abutting nodules extending toward an opposite facing surface and the other of said face surfaces comprises a ring of abutting v-shaped indentations for receiving said nodules therein to provide said contact between said clutch plate and said feed spool face surfaces.

4. A device as set forth in claim 3 wherein said ring of abutting nodules is formed on said feed spool and said ring of abutting v-shaped indentations is formed on said clutch plate.

5. A device as set forth in claim 1 wherein said biasing means comprises a spring disposed between a wall of said housing and said clutch plate.

6. A device as set forth in claim 1 wherein said take-up spool is of a lesser diameter than said feed spool.

7. A device as set forth in claim 1 wherein said take-up spool is of a lesser diameter than said clutch plate.

8. A device as set forth in claim 1 wherein each said housing, said feed spool, said take-up spool and said clutch plate are manufactured of a rigid plastic material.

9. A device as set forth in claim 2 wherein one of said face surfaces comprises a ring of abutting nodules extending toward an opposite facing surface and the other of said face surfaces comprises a ring of abutting v-shaped indentations for receiving said nodules therein to provide said contact between said clutch plate and said feed spool.

10. A device as set forth in claim 2 wherein said ring of abutting nodules is formed on said feed spool and said ring of abutting v-shaped indentations is formed on said clutch plate.

11. A device as set forth in claim 10 wherein said biasing means comprises a spring disposed between a wall of said housing and said clutch plate.

12. A device as set forth in claim 11 wherein said take-up spool is of a lesser diameter than said feed spool.

13. A device as set forth in claim 12 wherein said take-up spool is of a lesser diameter than said clutch plate.

14. A device as set forth in claim 13 wherein each said housing, said feed spool, said take-up spool and said clutch are manufactured of a rigid plastic material.
