 This
special design to be used with Emboss Tools are normally produced with spring loaded die and also for machines without active die or without ram from below.
However, there is always the problem that scratches appear on the bottom part of the sheet due to the heightened base of the tool as the sheet material will always be susceptible to
galling by moving of the sheet across the base.
In order to counteract this problem the machine user has several possibilities:
- Working with polished stripper made of ampco-material. However, the procedure of the galling can only be delayed in this case but not eliminated.
- The second possibility is to use soft pads. But this is still only a temporary solution and only suitable for a short period of operation.
In order to eliminate this long-term problem the engineers of PASS developed a simple, inexpensive, favourable and very effective solution.
Typically the evidence of galling always transpires on the extreme outer edge of the plate. Within this area a compressible rubber insert is integrated in the lower base from PASS, which
raises the sheet material within about 0,01 mm.
On the one hand this elastic rubber insert has the characteristic to support the sheet material weight when moving the sheet plate in order to suppress the contact of metal to
metal.
