ABSTRACT:
A slider inserting apparatus is constructed such that before a concealed fastener chain is threaded through a slider, the front and back and the rear end of a flange portion and the left and right front surfaces and the left and right side surfaces and the fore-end of a guide post are held between a pair of upper and lower slider holders with a locking pawl held in a releasing position. With the insertion of the fastener chain, the back and rear end of the flange portion is freed from engagement with the lower holder to enable passage of the fastener chain through the slider. The slider is still held from different directions by the holders so that in despite of a unique or odd shape of the slider, the fastener chain can smoothly be threaded through the slider. The slider inserting apparatus is preferably combined with a chain-reversing apparatus having element-reversing grooves, in which instance the top stop applying process and the slider inserting process can be carried out continuously on one and the same processing machine.
