Abstract
Abstract A sleeve shaped protector for a portion of a limb is manufactured from a sheet of cloth comprising a core of resilient, porous material laminated upon both faces with a sparse fabric. The sheet is cut to suitable size and rolled into a tubular member, whereupon a strip of fabric, being substantially non-resilient in its transverse direction is laid to cover the joint between the meeting edges of the sheet. The strip and the sheet are then sewn together using a machine having at least two needles to each side of the joint, the machine further having means for criss-crossing the threads from the needle to opposite sides of the joint, across the latter, at the face of the cloth remote from the strip.

Claim 1
Independent Claim

A method of manufacturing sleeve-shaped protectors for portions of the body and made of a sheet of cloth comprising a core of resilient, porous material laminated upon both faces with a coarse fabric, the sheet being cut to suitable size and rolled into a tubular member to thereby form a joint between the two meeting edges, comprising the steps of: locating a strip of fabric which is substantially non-resilient in its transverse direction along the joint between the meeting edges of the sheet, and sewing said strip to the sheet using a machine having at least two needles to each side of the joint, operating the machine for criss-crossing the threads from the needles to opposite sides of the joint, across the latter, at the face of the cloth remote from the strip.
