ABSTRACT:
An extruded T-shaped edge finishing strip has its tongue divided by a series of narrow abutting fingers of oblong section arranged in parallel and diagonally with their centers spaced along the original line of junction between the tongue and the face of the strip. Corresponding ends of the fingers are offset relative to the other ends of the appropriate adjacent fingers to enable the fingers to slide relative to each other or to spread apart as the face is bent as required by the curvature of the edge to be finished by the strip.
Apparatus for thus modifying the tongues of such strips has a flat support having a channel extending lengthwise thereof and dimensioned to receive the tongue of the strip with the undersurface of the face resting on the support. The channel passes between two gears having their upper faces substantially flush with the support, one gear a driving gear and the other one an idler, and the gears are spaced so that the tongue is such a force fit therein that the fingers are formed by the distortion of the tongues by the coaction of the gears.
