Strip guiding device

摘要

A strip guiding device for guiding a strip longitudinally along a feed path has a limiting mechanism for limiting the strip transversely at opposite side edges thereof to cause the strip to pass through a predetermined position in the feed path. The limiting mechanism has a pair of abutment members having respective abutment surfaces for abutting against the side edges of the strip along the feed path. The abutment members are movable in first directions toward and away from the side edges of the strip, and normally urged by a spring assembly to move away from the strip. The limiting mechanism also has a pair of pressing members having respective slanted surfaces held in sliding contact with respective sliding surfaces of the abutment members remote from the abutment surfaces. The pressing members are movable in second directions transverse to the first directions. The pressing members press the abutment members toward the strip against the urging means by sliding contact of the slanted surfaces with the sliding surfaces in response to movement of the pressing members in one of the second directions. The limiting mechanism further includes a displacing mechanism for displacing the pressing members in the second directions to move the abutment members in the first directions.
