Slider holder for attaching a slider to a fastener chain secured to an article

A slider holder for use in attaching a slider having a pair of guide channels to a pair of fastener stringers which are already secured to an article, wherein the fastener stringers are provided along a pair of opposed inside edges thereof with rows of fastener elements capable of elastic deformation, said slider holder comprising:

• a support structure having a slider mount on a top portion thereof, said slider mount having a top surface which is inclined at an angle to the plane of the horizon for receiving and positioning the slider upside down with the bottom end thereof directed downwardly;
• and means for locking the slider in position on said slider mount, whereby the fastener stringers may be threaded through the guide channels in the slider and forcibly pulled downwardly therethrough to adjust the relative positions of mismatched fastener elements by elastic deformation thereof, and then the stringers may be smoothly pulled back upwardly through the slider to engage the fastener elements.
