Step 1:
Wind any tape you would normally use to conduct a tape test, for example 600, 610, 810…,
through the equipment as shown. Any tape on a 3” core that is between 1/4” and 1”
wide will work.

Step 2:
To begin a test, tip the equipment up-right, grab the handle attached to the application brush and pull up to dispense a length of fresh tape for each test. Typical standards suggest approximately 3”, however, we’ve found it beneficial to use 7" or more to see patterns of adhesion.

Problems with Current Methods:
Tape on typical dispensers has area that is exposed to drying or debris. When done by hand, oils from fingers or other debris can get on the adhesive. Tape easily tangles.

Step 3:
Place the equipment on the area of the substrate to be tested. Return the brush to its home position. Note, the brush counter-rotates across the tape with consistent pressure and application motion, therefore this operation can be repeated by any operator.

Problems with Current Methods:
Bubbles or missed areas occur. Different application pressures, methods or patterns cause different bonds between the tape and the stubstrate. This is very difficult to
repeat by hand or from one operator to another.

Step 4:
Activate removal. When the tape removal is activated a roller is lowered to ensure the tape is removed at 180 degrees from the angle of application. Again, a repeatable action.

Problems with Current Methods:
It is nearly impossible for tape to be pulled at the same angle and rate by each operator, each time, by hand. Final results depend on how the operator performs each test.

Step 5:
Review results. A viewing area is provided in the front of the equipment. Use the same criteria you normally use or reference the appropriate standard. You have the option of removing the section of tape just used for testing to keep with your records/retains. Alternatively, you may record the date/job number on the tape and store on the spool as a record of performing the tests. You may also dispose of the tape neatly as the spool becomes full.

Problems with Current Methods:
Tape curls, tangles and sticks to fingers. Wads of tape end up strewn across work area. Tape must then be attached to the sample or another record.
