Abstract

The direct drive applicator for foil printing of the present invention discloses a light weight, portable, device advantageous in performing foil printing and laminating which is about the size of a type writer, and contains separate speed and temperature controls so that an operator can rapidly adjust the operation of the machine to quickly optimize the printing or laminating characteristics. The inventive machine contains a foil laminate supply reel and foil laminate takeup reel which are properly tensioned to provide an area of foil laminate under tension on both sides of a heated pressure roller to insure that crumpling or wrinkling of the foil laminate does not occur on printing.

Claims

1. A manually operated, manually activated foil applicator comprising:

a planar base housing;

a first and a second side support plate, spaced apart from each other and supported by said planar base housing;

a first elongate roller rotatably supported between said side support plates and rotatably powered;

a housing cover, supported by said planar base housing;

manually controlled heating means for controlling the temperature of said first elongate roller, supported by said housing cover and within said first elongate roller;

a second elongate roller rotatably supported between said side support plates and pivotally supported at a second axis parallel to said first axis and manually moveable out of engagement and into engagement with said first elongate roller;

a handle, connected to pivot with said second elongate roller, and extending beyond the limit of said housing cover, for enabling manual pivotally movement of said second elongate roller out of and into engagement with said first elongate roller; and

catch means, carried partially within said handle, and pivotable with respect to said handle, for locking said handle means into a first position where said second elongate roller is out of engagement with said first elongate roller and for releasing said handle means from said first position and bringing said second elongate roller toward engagement with said first elongate roller.

2. The applicator recited in claim 1 wherein said manually controlled heating means further comprises:

an electric heat element supported within said first elongate roller; and

a manual thermostat control supported by said housing cover for controlling the electrical energy delivered to said electric heat element.

3. The applicator recited in claim 1 further comprising:

a foil supply roll, rotatably supported by said side support plates, for dispensably feeding under tension a supply of foil sheeting between said first and second elongate rollers;

a foil take up roll, rotatably supported by said side support plates, for taking up said supply of foil sheeting under tension from between said first and second elongate rollers.

4. The applicator recited in claim 2 and further comprising a spring having a first end depending from one of said side support plates and a second end connected to said handle.

5. The applicator recited in claim 1 and further comprising:

an electric motor, supported by said planar base housing;

a chain sprocket mechanically connected to said electric motor;

a main drive sprocket mechanically connected to said first elongate roller; and

a chain connecting said main drive sprocket and said chain sprocket.

6. The applicator recited in claim 5 and further comprising a manually adjustable electric motor speed control, supported by said housing cover, and electrically connected to said electric motor.

7. The applicator recited in claim 5 and further comprising:

a pulley portion adjacent said main drive sprocket and mechanically connected to be rotatable with said main drive sprocket;

a pully mechanically connected to and rotatable with said foil take up roll; and

an elastic drive member connected between and drivably engaging said pulley portion and said pulley.

8. The applicator recited in claim 1 wherein said housing cover further comprises, a right side housing cover and a left side housing cover spaced apart from said right side housing cover housing and on opposing sides of said first and said second elongate rollers.

9. The applicator recited in claim 8 and further comprising a hot roller cover mounted between said right side housing cover and said left side housing cover and over said first elongate roller.
