Abstract: 1,271,313. Tubular films. UNION CARBIDE CORP. 17 April, 1969 [18 April, 1968], No. 19738/69. Heading B5B. [Also in Divisions A2 and D1] A method of inflating a collapsed tubular film (e.g. a casing for foods) comprises inflating the tubing with gas supplied under constant pressure and subjecting the inflated tubing to an initial net internal pressure (i.e. the pressure acting on the inside of the tubing minus the pressure acting on the outside of the tubing) and then to a lower net internal pressure, the change in the net internal pressure being created by changing the pressure exerted on the outside of the casing. The inflation may be carried out subsequent to a liquid treating step and prior to a shirring step. The inflated casing may be sized and dried. The casing may be made of collagen, alginate, starch, regenerated cellulose or polyolefin. In the embodiment shown, the casing 12 is treated in liquid bath 10, inflated with gas supplied through shirring mandrel 28 in chamber 18 connected to vacuum pump 32 and sized and dried in unit 34. The pressure in chamber 18 is less than that of the surrounding atmosphere and that in unit 34 so that the net internal pressure of the tubing in chamber 18 is higher than that in the unit 34, and in the surrounding atmosphere. The chamber 18 may be eliminated and a pressure pump 32<SP>1</SP> connected to the drier-sizer unit 34 to raise the pressure therein above that of the surrounding atmosphere so that the net internal pressure of the tubing in unit 34 is less than that in the tubing being passed to the unit 34.
