Abstract

A hand operated device for transferring a film from a carrier tape to a substrate is provided with a planar surface on its bottom wall, having a pair of laterally disposed flanges extending outwardly from the side walls, the side walls forming a hand gripping surface. An applicator bar over which a carrier tape is fed is spring biased downwardly to a point below the bottom planar surface, the point being such that the force required to raise the applicator bar to the plane of the planar surface is equal to the force required for laydown of the film onto the substrate. The device is operated by movement of the device over the substrate with said planar surface in contact with the substrate.

Claims

1. A hand operated device for transferring a film from a carrier tape to a substrate comprising

wall structure forming a housing for containing a carrier tape disposed on a reel, and reel means for accepting the tape after usage,

said housing comprising a pair of opposed side walls and a bottom wall, and an opening formed between said side walls adjacent the forward end of said bottom wall,

said bottom wall comprising a planar surface extending forwardly to said opening for contacting the substrate,

applicator means extending outwardly of said housing through said opening for supporting the carrier tape, said applicator means being free to move to a position above said planar surface, and

means biasing said applicator means downwardly to a point a predetermined distance below said planar surface said distance being calculated as that distance wherein a force moving said applicator means to a point whereat a tape disposed on said applicator means is in the plane of said planar surface, is at least equal to the force required for depositing the film from the carrier tape.

2. A hand operated device as set forth in claim 1 wherein said applicator means comprises an applicator bar having a surface extending transversely of said bottom wall over which the carrier tape is fed.

3. A hand operated device as set forth in claim 1 wherein a portion of said bottom wall planar surface is formed on a pair of laterally disposed flanges extending outwardly from said housing side walls.

4. A hand operated device as set forth in claim 1 wherein said applicator means comprises an applicator bar having a surface extending transversely of said bottom wall and having a lateral dimension substantially equal to the distance between the outer surface of said side walls, adjacent said planar surface, said side walls adjacent said planar surface being constructed to form a hand gripping portion of said device.

5. A hand operated device as set forth in claim 1 wherein the distance from said applicator means to said planar surface is in the area of 1 millimeter.

6. A hand operated device as set forth in claim 1 wherein the force moving said applicator means to a point wherein a tape disposed on said applicator means is in the plane of said planar surface is in the area of 600 grams.

7. A hand operated device as set forth in claim 1 wherein the distance from said applicator means to said planar surface is in the area of 1 millimeter and the force moving said applicator means to a point whereat a tape disposed on said applicator means is in the plane of said planar surface is in the area of 600 grams.

8. A hand operated device as set forth in claim 3 wherein said planar surface extends laterally a distance at least 11/2 times the distance between said side walls.

9. A hand operated device as set forth in claim 2 wherein a portion of said bottom wall planar surface is formed on a pair of laterally disposed flanges extending outwardly from said housing side walls.

10. A hand operated device as set forth in claim 9 wherein said applicator bar has a lateral dimension substantially equal to the distance between the outer surface of said side walls, adjacent said planar surface, said side walls adjacent said planar surface constructed to form a hand gripping portion of said device.

11. A hand operated device as set forth in claim 10 wherein the distance from said applicator bar to said planar surface is in the area of 1 millimeter.

12. A hand operated device as set forth in claim 10 wherein the force moving said applicator bar to a point wherein a tape disposed on said applicator bar is in the plane of said planar surface is in the area of 600 grams.

13. A hand operated device as set forth in claim 10 wherein the distance from said applicator bar to said planar surface is in the area of 1 millimeter and the force moving said applicator bar to a point whereat a tape disposed on said applicator bar is in the plane of said planar surface is in the area of 600 grams.

14. A hand operated device as set forth in claim 9 wherein said planar surface extends laterally a distance at least 11/2 times the distance between said side walls.
