Title: Methods of corrugating sheets of asbestos cement or the like and corrugating machines suitable for carrying out the methods
Inventor: SLYTER HEINRICH SOFUS
IPC: B28B1/52
Filed: 1959-06-15
Abstract: 849,197. Corrugating asbestos-cement sheets. SMIDTH & CO. A. S., F. L. June 15, 1959, No. 20492/59. Class 87(2). Sheets of asbestos cement are corrugated, while plastic, in a machine which comprises an upper member 7 with a working surface conforming to the required corrugations and a lower member 8 with rollers A, B, C, D conforming to the valleys of the upper member and carried on the upper ends of pistons 12 of compressed air cylinders 13. The middle roller A is first raised to press the middle part of the sheet into the correspondihg valley and the remaining rollers B-B, C-C, D-D are moved in succession to complete the corrugation. Compressed air is distributed to the cylinders by a known device 15 operated automatically by a rod 18. To reduce friction and lessen the risk of the sheet cracking as it is corrugated, chains 35, 36, fixed at one end to the support 37 of the roller A pass round sprocket wheels B 1 , C 1 , D 1  on the shafts of the rollers B, C, D and round sprocket wheels ba, ab &c. on shafts carried by the framework and terminate in weights or springs 37, 38, the operation being that when the roller A rises, the remaining rollers are positively rotated in the direction of the movement of the sheet, the same rotation being imparted to the remaining rollers when the rollers B 1  C 1  and D 1  are raised. The upper moulding member 7 is hollow and when all the rollers are pressing against it, i.e. when the corrugation is complete, a valve 20 in a partly flexible pipe 19 is set to connect it to a source of vacuum and the sheet 9 thus remains on its lower surface when the rollers are lowered. The moulding member 7 is suspended in a carriage 21 which is pushed, along rails 23, above a table 28, and a valve 26 is then actuated to cause the piston-rod 25 of a cylinder 24 to deposit the sheet, the valve 20 being simultaneously actuated to connect the moulding member 7 to atmosphere. By a similar operation a vacuum pick-up device 29, raised and lowered by a cylinder and piston 40, 39 and connected to vacuum or atmosphere through a pipe 31, picks up a fresh sheet from a conveyer 33 and deposits it on the rollers of the lower member 8.

IPC: D03D41/00
Filed: 1923-08-20
Abstract: 216,025. Friend, J. Aug. 20, 1923. Slat fabrics, looms specially designed for; shuttleless looms.-In a machine for weaving slat blinds, flat slats of wood or metal are fed from an adjustable hopper 15, Fig. 3, by reciprocating stripper-plungers 40 having chisel edges 41, entering between the lowest and the next lowest slat, and blunt chisel edges 42 for feeding the lowest slat forwards between the forward split extensions 13, 14, Figs. 3, 4 and 5, of rotary sleeves 12, which are intermittently rotated by worm and interrupted spur gearing furnished with spring-controlled locating check-devices 86. The upper extension or cap 14 is separate from the part 12 and is moved vertically against the action of springs when a slat is fed forwards so as to act upon an inclined part 20 of the cap, thus forming a division between the parts 13, 14 through which the slat is fed to the weaving point. The plungers 40 fit through central holes 19 in the sleeves. The warp cords or wires 26, which are twisted around the slats to connect them together are carried by spools 21, 22 on spindles 23 supported' in spring bracket-arms 24 furnished with cork washers 25 acting as brakes and carried by the parts 13, 14, so as to rotate with the sleeves, the cords &c. passing through guide-sleeves 68 and through holes 31, 27 in glass or porcelain thimbles 80, 81 on the parts 13, 14 to the weaving point, where they are twisted around the slat that has been fed forwards. This slat is retained in position against rear movement by spring pawls 69, and is pressed by spring shoes 32 on to a horse or carrier-bed 33. The slats are nicked' at 70, Fig. 7, by the plungers and the twisted cords fit in these nicks. The weight of the slats checks the rotation of the sleeves 12 and locates these sleeves during the dwell in their rotation with the slat beds thereon disposed horizontally. The woven fabric formed by the flexibly-connected flat slats passes into a take-off race 34. The plungers are reciprocated by crank mechanism, which is described.
