This machine is used for testing the initial adhesion of pressure sensitive tapes
Obliquity range: 0 to 60°
Width of testing table: 120mm
Width of resting area: 80mm
Standard steel balls: 1/32 to 1 inches
Dimensions: 320 x 140 x 180mm
Standard configuration: testing machine, 32 testing steel balls
Testing standard: GB 4852/JIS Z0237
Step 1: stick about 20mm tape on the slant surface of machine
Step 2: let the steel ball fall on the slant surface
Step 3: when the ball falls off, there is slight pressure between the ball and tape, so we test the initial adhesion by the sticking ability of the ball to the tape
