Title: Improvements in or relating to method and apparatus for tensioning strip material
Inventor: COLLINS DON FREMONT
IPC: B29D29/00
Filed: 1952-08-06
Abstract: 721,177. Feeding webs. BOSTON WOVEN HOSE & RUBBER CO. Aug. 6, 1952, No. 19802/52. Class 100 (1). [Also in Groups V and XXIX] In a continuous feeding device for strip material, the material is drawn over a rotatable cylindrical surface and a frictional rotary torsion is maintained on said surface tending to rotate it in a direction opposed to the movement of the material, the torsion being varied in inverse ratio to the tension on the material passing from the cylindrical surface so that a uniform tension is maintained in the material. In a continuously-operating machine for stretching rubber and vulcanizing it, a web of the material is drawn from a supply roll 16, Fig. 1, and passes in succession over an idler 18, a tensionregulating roll 20, a tension-measuring roll 22, an idler 24, a series of rolls 25 ... 28 the speeds of which progressively increase from 25 to 28 so as to stretch the rubber, an idler 30 and, finally, over a vulcanizing roll 14 against which it is held by supporting rolls 11, 12. The drives to the rolls 25 . . . 28 are taken from various intermediate points in a chain of gear wheels, and each drive is through a manuallyoperable clutch so that any desired amount of stretch can be given to the material by disconnecting the drive from the appropriate roll or rolls. The final amount of tension required is put into the material by urging roll 20 to rotate against the direction of travel of the web and by pressing the web into contact with roll 20 by means of a presser roll 54 urged towards roll 20 by pneumatic jacks 58, Fig. 7. Jacks 58 and a pneumatically-actuated clutch 62 in the drive to roll 20 are actuated in accordance with the measurement of the.tension in the material as detected by roll 22. The latter is mounted eccentrically on a shaft 78 which is rotatably mounted in the framing of the machine and which carries a lever 80. The free end of the latter can move between a pair of stops and it is urged towards the upper stop by a diaphragm 92 subject on its underside to a pneumatic pressure derived from a pressure regulator 98. The line 66 supplying pneumatic pressure includes a bleed 102 and a throttle valve 84 connected to lever 80 so that, as the position of roll 22 is determined by the tension in the material, the actuation of clutch 62 and jacks 58 will also be determined by that tension. The system can be exhausted by means of a hand-operated valve 72.

Title: Method and apparatus for machining rolls for rolling mills and the like
IPC: B23Q35/08
Filed: 1931-07-10
Abstract: 375,565. Shaping rolls for rolling- mills. MANNESMANNROHRENWERKE, 1B, Berger Ufer, D³sseldorf, Germany. July 10, 1931, No. 19895. Convention date, Jan. 28. [Classes 83 (ii) and 83 (iii).] In a method of and apparatus for machining rolls such as Pilger rolls, each roll R is cut by a tool which rotates about a transverse axis as described in Specification 353,829, but the inclined sides of the roll profile are obtained by axial displacement of the roll during the rotation of the tool holder. A main shaft 1 is connected through bevel gears 2 and spur gearing 5 to a rotary arbor 7 which is fitted with a shoe 13 carrying the holder of the tool 8. The shoe may be moved radially of the arbor by means of a rack bar 10 acting through a pinion 11 and rack 12 and operated by a sleeve 9 which is moved vertically by a threaded member 33 driven by worm gearing 32 from a shaft 31. Each roll carries a worm gear 19 driven from the shaft 1 through chain gearing 14 and shaft 15 to rotate the roll slowly and feed it past the tool. The shaft 1 also drives a shaft 21 connected to vertical spindles 26 each carrying a cam drum 27 which imparts movement through an arm 28 to a carriage 29 carrying the rolls, this movement taking place while the inclined sides of the rolls are being machined. Each drum 27 is of varying cross section to give different inclinations of the roll sides. For moving the cam drums vertically a screwed sleeve 35 is engaged by a nut 34 driven by worm 34<1> on a shaft 30 which may be rotated either manually or from the shaft 31. Alternatively, the movements of the drums 27 may be controlled by templets or by servoapparatus. The angle alpha, Fig. 3, subtended by the inclined side of the roll may be varied by imparting a supplementary rotation to the drums 27 by reciprocation of the shaft 21 by means of an adjustable crank which is rotated at twice the speed of the arbor 7.
