Abstract
Abstract The respective ends of a heavy fabric, for example, a woven dryer fabric or felt each provided with an array of connectong loops are joined with the help of a gap closing device. The gap closing device is detachably attached to the fabric when the latter is supplied to the user. When the fabric is being installed on the machine, the ends are pulled together by the gap closing device so that the arrays of loops are held in proximity and easily intermeshed to form an elongated tubular passage. A pintle wire is inserted into the passage to complete the joint. The gap closing device is then removed. A preferred gap closing device is a slide fastener, of which one tape is detachably attached to each end of the heavy fabric.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
132 words
In a method of drawing together into juxtaposition the ends of a wide heavy fabric, against resistance of said ends to being drawn together, each end being provided with an array of loops spaced apart in the lateral direction of the fabric and adapted to be intermeshed and brought into register to form an elongated tubular passage for receiving an elongated holding member to form a hinge-type joint, comprising the step of, connecting a side of a gap closing device detachably laterally along each of the respective ends with complementary progressive fastening means of the device on each side extending from one edge to the other ready to be engaged to draw the ends of the heavy fabric together in increments and thereafter retaining the increments together in a relative holding position.

Claim 5
Dependent Claim
139 words
A wide heavy fabric having respective ends to be pulled together and their edges joined to form an endless band, the edge of each of said ends being provided with an array of loops spaced apart in the lateral direction of the fabric and adapted to be intermeshed with the array of the other edge to form an elongated tubular passage for receiving a pintle to complete a hinge-type joint, the improvement in which, one side of a gap closing device having respective interlocking means is attached to each of said ends for drawing the respective ends together progressively starting at one side edge of the fabric in continuous increments and thereafter retaining the increments together in a relative holding position from which the loops of the respective arrays can be readily intermeshed manually to form said elongated passage.
