Abstract
Abstract A meeting rail for application to overlapping marginal edge portions of sliding window panes when the panes are closed having a strip of semi-rigid thermoplastic material with longitudinally extending spaced apart ribs of flexible thermoplastic material being fused to the semi-rigid thermoplastic material and extending from one side of the strip and a pressure sensitive adhesive on the opposite side of the strip to enable the rails to be secured in pairs to said edge portions, height and spacing of the ribs being such that the ribs of opposing rails are disposed in interdigital relationship when the panes are closed.

A meeting rail assembly for application to over-lapping marginal edge portions of closable sliding window panes comprising: (a) a pair of meeting rails, one for each window, (b) each meeting rail comprising: (i) a pair of parallel planar strips of semi-rigid thermoplastic material having inner and outer side surfaces, (ii) a connecting strip of flexible thermoplastic material extending parallel to and positioned between and fused at its edges to adjacent edges of the semi-rigid strips, (iii) a plurality of parallel, longitudinally extending spaced-apart ribs disposed on the outer side surface of one of the semi-rigid strips of each rail, said ribs being of a flexible thermoplastic material and being fused to said one semi-rigid strip, (iv) a pressure sensitive adhesive on the inner surfaces of the semi-rigid strips for enabling the meeting rails to be applied and secured to said marginal edge portions of the panes in a position in which the ribs of opposing rails extend in inter-digital relationship when the panes are closed.
