650,845. Combing machines. WHITIN MACHINE WORKS. Feb. 3, 1948, No. 3106. Convention date, Nov. 8, 1946. [Class 120(i)] [Also in Group XXIV] A planetary roll drive for a combing machine comprises a drive shaft 10, a drive gear 11 secured to the drive shaft 10, a second shaft 14 parallel to the drive shaft, a first driven gear 13 mounted on the second shaft and meshing with the drive gear, a second driven gear 23 mounted on the second shaft, a planet gear 19 meshing with both the first and second driven gears, a planet stud 20 supporting the planet gear and a planet stud supporting arm 21 mounted on said second shaft with freedom to oscillate relatively to the driven gears. As shown, the second shaft 14 is a rock shaft, the driven gears 13 and 23 being freely mounted thereon and the planet stud supporting arm 21 being secured thereto. The rock shaft is oscillated by means of cam roll 34 mounted at the end of a crank arm 35 secured to rock shaft 14, the cam roll 34 running in a track 33 in the cam wheel 32 secured to the drive shaft 10. The oscillation of the shaft 14 swings the compound planet gear about the axis of shaft 14 thus increasing or decreasing the speed of rotation of the gear 23 and thus the speed of rotation of the detaching rolls 26 and 27 which are geared thereto. The mechanism is so designed that the speed of the detaching rolls follows the following cycle:-acceleration, uniform speed, deceleration and reversal. The reverse rotation serves to feed back the previously detached tuft to receive the succeeding fringe in overlapped relationship.
