PURPOSE:To enable the use of a fastener of a uniform width corresponding to the width of the small-width end of a window frame of gradually decreased width, by bonding the base plate of the fastener to engage lace on different- dimension clips engaged in the clip holding groove of the fastener. CONSTITUTION:The base plate 2a of a fastener 2 of a uniform width corresponding to the width W of the small-width end of a window frame 1a, the width of which is gradually changed in the vertical direction, is bonded on the front edge 1a' of the frame. Clips 5, 15,..., in which the width of lace engaging portions 5a, 15a,... are sequentially increased away from the small-width end, are engaged at vertical intervals in a clip holding groove 4. Lace 6, width is gradually increased, is engaged on the lace holding portions 5a, 15a,... of the clips 5, 15,.... This constitution enables the use of the uniform-width fastener which can be continuously formed. |
