ABG STRETCH TAPE

Abstract

An adhesive elastomeric tape comprising 90 grade cheesecloth that is knitted with a medium gauge elastic yarn through a stitch bonding machine. The cloth is then coated with a petroleum base adhesive using a unique strike through method that allows a adhesive to pass through while coating both sides. A style of athletic tape that is flexible, durable, and adhesive simultaneously.

Description

BACKGROUND OF INVENTION

The present invention is in the technical field of sports and athletic equipment. More particularly, the present invention is in the technical field of athletic tape. Current tapes on the market either lack flexibility, durability, or adhesiveness; never incorporating all three. The most common athletic tape is 100% cloth and used for many purposes within the sporting world, such as wrapping a hockey stick or holding fingers together. While standard athletic tape can protect skin its use in weightlifting and other sports it is not ideal. While using a weighted barbell, standard athletic tape's lack of flexibility commonly causes bruising and swelling on the skin under the tape. Other tapes that use a combination of cotton and polyester provide decent durability and flexibility but lack strong adhesive, causing the tape to unravel and fail its intended use.

SUMMARY OF THE INVENTION

The present invention is an athletic tape designed to be adhesive, flexible, and durable simultaneously; allowing athletes to achieve optimal performance. This specific athletic tape is ideal for wrapping the thumb to improve the hook grip in weightlifting, wrapping forearms to protect from atlas stones in strongman competitions, covering shins to prevent barbell cuts and wrapping the entire palm of hand to protect a torn callus which is common amongst athletes. Other common uses include wrapping baseball bats and tennis rackets for grip, taping fingers for golf, wrapping wrists during judo, fingers for fishermen and ankles for ice skaters.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the invention in more detail, FIGS. 1 and 2 show athletic tape that was manufactured by feeding 90 grade cheesecloth into a stitch bonding machine that knits in the elastic yarn. The stitching is designed to allow stretch along the length, but none along the width. Weaving this specific number of threads of elastic into the highest grade cheesecloth provides comfort, flexibility and durability.

Adhesive is then applied using a knife-over-roll coating technique to attain a “strike through” effect. This unique coating provides adhesive on both sides of the tape. The coating is applied with the fabric stretched fully extended and then immediately relaxed prior to entering the heated drying ovens to allow the tape to maintain its high stretch capabilities.

The finished product is extremely flexible, easily hand tearable, very adhesive and durable. These combined qualities make this tape unique in the industry.

Claims

1. A method of making knitted elastomeric adhesive tape comprising the steps of: wherein the base fabric material is composed of natural, unbleached, Grade #90 cheesecloth; which is a 100% cotton fabric loosely woven with a 44×36 thread count per inch;wherein an elastic 105 denier thread is composed of raw, semi dull and opaque, non-twisted, 100% Spandex. This is a high strength, high uniformity, bare spandex yarn with a 20% expansion rate;wherein the adhesive is Hero Coatings #310; a High Solids Tape Compound which is composed of natural and Styrene-Isoprene-Styrene Rubber (SIS) polymers with 71% solids +/−3% and solvent by Heptane/Toluene;operating a stitch bonding machine to knit said thread in 12 threads transverse per inch and 8 stitches longitudinal per inch into the Grade 90 Cheesecloth;operating a knife-over-roll coating machine to attain complete surface coverage of said adhesive on said fabric with a dried thickness of 5 mills on surface one, and a strike-thru of the adhesive to create a dried thickness of 1 mil on surface two;operating fabric is stretched to maximum tension to create a full stretch during coating process and subsequently decreased to a relaxed state prior to entering the curing/heat tunnel;

2. The method of claim 1 wherein the fabric has zero transverse stretch and 75% longitudinal stretch.
