Abstract
Abstract A method of making a luggage case including the steps of forming a pair of frame members adapted to abut in interlocking relationship, attaching the material which, together with the frame members, forms the peripheral surface of the case to said frame members while they are in a substantially linear condition, bending the framework and the material attached thereto to the required shape of the outer periphery and attaching to the resulting peripheral surface the side panels, lining and other necessary accoutrements. The luggage case resulting from the method of construction has no passage for dirt, water and the like to enter the luggage case at the place where the framework is attached.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A method of manufacturing a luggage case comprising the steps of; a. cutting a pair of interlocking frame members each having a pair of integral, spaced, outwardly facing flanges to a length predetermined by the size of the case to be manufactured, b. placing fabric between the flanges, c. squeezing the flanges together by passing the frame member with the fabric in place between a pair of contoured rollers, said rollers being shaped to apply pressure and compress only the flanges of the frame member thereby frictionally holding the fabric, d. bending the frame into a desired configuration forming the peripheral edge of the sides of the case, e. attaching the side panels and adding hardware necessary to complete the luggage case.
Claim 2
Independent Claim
122 words

Claim 3
Dependent Claim
20 words
A method as in claim 1 wherein the interlocking frame members each include an integral reinforcing rib extending outwardly therefrom.
Claim 4
Dependent Claim
30 words
A method as in claim 1 and further including the steps of cutting a pair of fabric pieces to a predetermined size prior to placing the fabric between the flanges.
Claim 5
Independent Claim
116 words
A method of manufacturing a luggage case comprising the steps of cutting a pair of interlocking frame members each having a pair of integrally spaced outwardly facing flanges to a length predetermined by the size of the case to be manufactured, placing fabric between the flanges, squeezing the flanges together, thereby securing the fabric to the frame, bending the frame into a desired configuration forming a peripheral edge for the sides of the case, attaching the side panels to the peripheral fabric by means of a bead having outwardly extending flanges, sewing the side panel to one flange, sewing the peripheral fabric to the other flange and adding the hardware necessary to complete the luggage case.
