Abstract

1,265,330. Making cylinders. P. L. PANIGATI. 22 April, 1969 [26 April, 1968], No. 20486/69. Heading B3A. A method of making a cylinder for a fluid operated piston-cylinder assembly comprises making a sheet of dimensions corresponding to the development of the cylinder to be made, forming apertures 2 and 3 in the sheet corresponding to inlet and outlet ports and fixing devices (8) for end portions of the cylinder (4), Fig. 1 (not shown), by a single pressing operation, winding the sheet into a cylinder and welding the adjacent edges 5 together to form the cylinder. A cylinder liner (6), Fig. 1 (not shown), whose outside diameter is equal to the internal diameter of the cylinder is fitted to cover at least the central part of the cylinder. Slots 10 for use with an adjustment device may also be made during the pressing operation.
