Title: Improved method of and machine for folding sheet material into bellows
Filed: 1951-01-23
Abstract: 717,909. Making paper &c. tubes. GENERAL MOTORS CORPORATION. Jan. 23, 1951 [Jan. 24, 1950], No. 1671/51. Class 99 (2). [Also in Groups VII and XVI] A machine, for folding continuously moving sheet material into bellows form, comprises pleat formers continuously movable inwardly and longitudinally of the material, in tube form, and then outwardly from the folds, and means for supplying air under pressure internally of the tube whilst it is being folded. Strip material supplied from a roll 18, Fig. 1, has adhesive supplied to its lower and upper edges by glue nozzles 28 and 52 which are horizontally and vertically adjustable relatively to the strip which passes over a platen 22 and then under an arm 56 overlapping the flat end 58 of an external former 60. The former 60 gradually changes, along its length, from a flat to a substantially cylindrical shape as shown in Fig. 6, so as to form the strip into a tube. An internal former 62 is supported within the former 60 by a hanger 64. Beyond the former 60 a pair of longitudinally adjustable semi-cylindrical guides 92, Fig. 1, completely surround the tube. The tube then passes through two frames 112 and 222 of similar construction, each frame being in two parts, such that a lower part 116, Fig. 8, is pivoted to an upper part 120. The frame carries driven rollers 138, 154, 202 and 172 which cooperate with rollers 206 freely mounted in the former 62 to feed the tube longitudinally, the roller 172 being of metal and having an electric heating element 174 which dries the adhesive coating in the tube. The shape of the former 62 changes to square cross-section beyond the frame 222 and is then sharply tapered at 240, Fig. 12, to form a square extension 242 corresponding in size to the aperture of the bellows to be formed. The tube is supported during folding by compressed air supplied through a pipe 78, Fig. 1, a passage 218, Fig. 8, in the former 62, and holes 244. The folding mechanism, Figs. 1 and 12, comprises four series of formers 260, 262, 264 and 266 each consisting of trapezoidally-shaped formers 268 each having a pair of ears 272 engaging a pintle on an adjacent former, pins 274 passing through the pintle and ears, such that the formers constitute an endless chain extending over synchronously driven sprockets 278, 276, the drive.being transmitted to the sprockets by bevel gearing from a shaft 282 below the extension 242 and carrying one of the sprockets 276. The shaft 282 is driven by a chain 306 and sprocket 304 from a gear box 232, while a shaft 284 carrying the sprockets 278, is driven by a pair of pinions from a pinion on the shaft 282. Thus, the top and bottom formers 260 and 262 engage the now square-section tube supported by compressed air around the extension 242 to form top and bottom pleats in the tube which is then pleated by the formers 264 and 266, the process being continued to form alternate top and bottom and side pleats. Reference has been directed by the Comptroller to Specifications 672,961 and 680,263, [both in Group VII].
