Abstract

A method of forming a fabric covered end on a wallboard spline structure is disclosed herein. A fixture is provided with a series of recesses to position the fabric and the spline in a desired relationship. An adhesive is provided on a portion of the vertical web of the spline and the inserting of the fabric and the spline into the fixture positions the fabric on the desired portion of the spline.

Claims

1. A method of forming a fabric-covered end on a wallboard spline structure comprising the steps of:

(a) providing a fixture with a three-step recess of an upper larger recess, lower smallest recess, and an intermediate recess to receive the end of a spline structure with four flanges, the end of the spline structure to be covered with a fabric material, said lower smallest recess being sized to have the fabric covered end fit snugly therein;

(b) further providing the fixture with a base and guide means to position the fabric laying flat above the lower smallest recess with the fabric material edges located an equal distance either side of the lower smallest recess, said guide means also guiding the ends of the flanges of the spline so that the end of the spline structure is received in the lower smallest recess, said intermediate and upper recesses having wall means which form the guide means;

(c) placing an adhesive coating on the fabric;

(d) placing the fabric on the base above the lower smallest recess in the fixture and properly locating said fabric above the lower smallest recess of the fixture by the guide means of the large and intermediate recesses; and

(e) inserting the end of the spline, properly centered by the guide means engaging the end of the four flanges, into the fixture lower smallest recess and, at the same time, forcing the fabric material around the end of the spline structure so that the adhesive bonds the end to the fabric.
