Precision feed and guide system for sub-100 micron thickness metal foil sheets

A feed and guide system for sub-100 micron metal foils comprising:

• a lower drive roller paired with an upper follower roller;
• an ironless core drive motor coupled to the lower drive roller;
• a lower forward fixed guide platen;
• an upper forward guide platen slidably movable relative to the lower forward fixed guide platen along a foil feed path, said upper and lower forward guide platens interfitting and cooperating to define a forward output guide channel forward of the roller pair,
• a lower rearward fixed guide platen;
• an upper rearward guide platen slidably movable relative to the lower rearward fixed guide platen along the foil feed path, said upper and lower rearward guide platens interfitting and cooperating to define a rearward input guide chanel rearward of the roller pair,
• wherein the upper forward and rearward guide platens are removable from the lower forward and rearward guide platens for initial feeding of a foil sheet into the guide channels,
• a plurality of complementary magnet pairs mounted in corresponding facing relation in opposing surfaces of the upper and lower, forward and rearward guide platens wherein opposing magnetic poles of the complementary magnet pairs are axially offset to create a biased attraction of the forward and rearward upper platens toward the rollers;
• and
• symmetric left and right adjustment stops in each of the forward and rearward upper and lower guide platens to fix respective forward and rearward sliding movement of the upper guide platens relative to the lower guide platens.
