Abstract

An offset, double-sided tape dispenser. The dispenser mounts two independent rolls of single surface adhesive tape on a common spindle. One of the rolls is inverted resulting in one roll wound clockwise and the other roll wound counter clockwise. The tapes are simultaneously drawn from the two rolls through a guide, across a roller and then a cutter. The clockwise wound roll tape has its adhesive surface facing upward as the tape crosses the roller. The counter clockwise wound roll tape has its adhesive surface facing downward as the tape crosses the roller. The clockwise wound roll tape is positioned beneath the counter clockwise wound tape as the tape passes through the guide. This results in the counter clockwise tape being joined to the clockwise tape as both tapes pass over the roller. The resulting double sided adhesive tape is then formed into desired lengths by the cutter. The degree of single tape overlap, resulting offset and resulting width of the resulting double sided adhesive tape is determined by the width of the guide.

Claims

1. An offset, double-sided tape dispenser for dispensing an offset, double sided tape formed from two single sided tapes, comprising:

a dispenser having a bottom base, an open top, two opposite sides, a front and a rear, said bottom, top, sides, front and rear defining a dispenser hollow interior, said dispenser front and rear defining a dispenser longitudinal axis;

a rear aperture formed in each dispenser side, near to the dispenser rear and dispenser top;

a single tape spindle mounted laterally the dispenser interior and extending through each said rear aperture, said tape spindle having two ends protruding through the dispenser side rear apertures;

a forward aperture formed in each dispenser side, near to the dispenser front and dispenser top;

a roller having two ends mounted laterally within the dispenser interior with a forward fastener attached to each roller end;

two vertical guides within the dispenser interior, each guide being positioned adjacent a dispenser side directly opposite the other guide;

said guides longitudinally positioned between the roller and the tape spindle;

a lateral cutter attached to the dispenser front at the dispenser top;

two rolls of single sided each mounted on a spool, each said roll having two surfaces, one surface with an adhesive and the other opposite surface being adhesive free, said tape roll spools being mounted on said spindle, one spool being inverted, resulting in one tape roll wound clockwise and the other tape roll wound counter clockwise;

wherein said tape is adapted to being simultaneously drawn from each roll toward the dispenser front, across said roller and said cutter, said clockwise wound roll tape having its adhesive surface facing upward and the counter clockwise wound roll tape having its adhesive surface facing downward, said to tapes being joined on the roller as the tapes pulled toward the dispenser front thereby forming a offset, double sided tape;

wherein said guides are adapted to forcing said drawn tape to overlap thereby determining the offset between tapes and a resulting width of the offset double sided tape;

wherein the roller has a lateral axis positioned vertically higher than a cutter lateral axis;

wherein said vertical guides are adjustable, and are comprised of an adjustable guide mechanism comprising;

two elongated, vertical posts, each post terminating at a lower end in a shoe slidably resting on the dispenser bottom within the dispenser interior;

two guide apertures formed in each dispenser side, longitudinally positioned between the forward apertures and the rear apertures;

an elongated threaded element fixedly attached to each said vertical post, each said threaded element having a first threaded nut threadingly attached thereto, each threaded element being extended through a guide aperture and engaged by a second threaded nut;

wherein manipulation of the threaded nuts permits the operator to adjust the distance between both guide posts and thereby the offset between tapes, and the resulting width of the double sided tape.
