E: Is the distance from the center of the upper row of holes to the edge of the strip, with a dimensional tolerance of 1.75 ± 0.1mm. If it is greater than the tolerance, the track will not pass through. If it is less than the tolerance, the edge will be broken due to insufficient strength

D: The diameter of the upper row of holes is 1.5 ± 0.1mm, and this circle can only be large but not small. Because the diameter of the pinhole driven by the general packaging machine is 1.5mm, if it is too small, the pinhole will not pass through, resulting in shutdown

D1: the diameter of the center is 1.5 ± 0.1mm. The function of the center hole is to let the bottom detection lamp detect whether there is a workpiece in the forming groove. The diameter of the center hole with a bandwidth of 12-24mm is 1.5 ± 0.1mm; 32-88mm bandwidth center hole diameter is 2.0 ± 0.1mm—embossed carrier tape

P0: is the distance between the center of the upper row of holes and the center. The distance between the center holes is 4.0 ± 0.1mm. If the size is too large or too small, it will directly affect the instability of P2 size. At the same time, the pinhole of the packaging machine cannot drive the original belt, resulting in machine failure and shutdown

P2: is the distance between the left and right centers of the upper row holes and the left and right centers of the forming groove. If the center position is moved, the workpiece will be offset and unable to be placed or the center point of the product cannot be absorbed during suction

T: Raw material thickness. The deeper the K0 is, the thicker the raw material is. On the contrary, the shallower the K0 is, the thinner the raw material is

S0: is the distance between the upper row of holes and the lower row of holes—embossed carrier tape
