In the carrying'out or the invention herein, this knockdown orrflat tubular structure (Fig. 2) may be spread or opened out and the side walls 5 (Fig. 4) then thrust toward .a base I2 having shallow inwardly tapered portion II.

Helptul in carrying out this invention is a machine having an overhanging arm II, terminally of which is located a stitcher 21, for flat stock adapted to be cut into lengths and terminally bent over as a two-pointed tack in staple-like type or stitch. A column 48 has thereon a lower deck or holder II and an upper deck or holder table II. The location or the table portion II is at such spacing from the table portion II that,

registers with the scoring II stitcher 21.

As shown in Fig. 9, the fractional tab II at its edge portion from the terminus of the side portion 3 is away from registering with a notch II. This means that the clearance H as to at least one of the overlapping termini oi the sides I. I, assembled by the stitching I, has clearance continuity away from a notch II. The notches iI are suflicient to permit the tabs H to be swung toward each other into a common plane withthe disk it, with minimum 01' crowding action at the clearance II as away from the seam. This is a factor in promoting sealing eillciency, even for aggravate or tend to promote In placing this stock or work on the holder,
