The relative speed between the perforation elements on the surface of the pattern roll and the anvil surface shears the web at the perforation points.

Depending on the relevant general direction of the contour and the deviations from the contour points the piercing points are selected and memorized.

Recesses (11) which define puncturing points (16) are formed on one face (9) of the band-shaped support material (1).

Then puncture with a small adjacent signal points are marked and the remains of the droplets are cleaned.

The perforating points are marked by RF coupling points (10) and are softened by means of RF energy in order to achieve dielectric breakthroughs (11) there.

The plungers are provided with predetermined perforation points, which enable the liquids to come in contact with the target substance in a desired sequence and volume.

This file indicates the information of the type of stitches, color of the thread, points of perforation and quantity that the machine will need to perform the embroidery.

The breakthroughs (11) are widened into holes (12).

Having puncture or rust spots in the oil pan can lead to a number of different issues.
