Abstract
In the manufacture of film containing integral fasteners and the like, the film commonly exits through an elongated slot die while profiles for the fasteners exit through a smaller configured slot located laterally along the film die slot. The fastener profiles normally carry a thickened base so that the profiles will stand without undue tipping for better interengagement with one another. It has been found that it is advantageous if the base of the profile can be adjusted transversely of the film slot so that the size of the base can be adjusted on-line. The present invention allows the die block to be transversely adjustable by a combination of a U-shaped mounting block, an inverted T-shaped profile plate and an eccentric adjustment pin, assembled in a fashion so that the eccentric pin can be rotated to adjust transversely the gap through which the profile base passes just before joining the film. This device also makes possible measurement of the gap for the profile base indirectly on line.
