Abstract: 24,037. Marks, E. C. R., [Cameron Machine Co.]. Dec. 14. Feeding and winding webs.-Relates to a machine for slitting and winding webs, of the type in which the feeding-roller is driven at a constant speed and the winding-roller is driven by means including a slip device to allow for the variations in speed of the winding-roller as the wound material accumulates thereon, the winding - roller being carried by pivoted arms, and consists in the following features: the arrangement on t h e pivoted arms of trains of gear-wheels for driving the winding-roller; the arrangement of the slip device on the axis of the shaft carrying the pivoted arms; a ratchet arrangement to hold these arms at different heights; a braking-means for holding the winding-roller under tension against the feeding-roller; an automatic counterweight to relieve the feed-roller of the increasing weight of material on the winding- roller; and an arrangem e n t of detachable sliding-sleeve joint sons to remove a fully wound winding - roller quickly. A roll 3 of web material supported on the framework 2 passes o v e r guide - rollers 4 .. 8, between the cutter 11, held by arms 12 and springs 14, and the feeding - roller 10, round another guide-roller 37, to the rewinding-roller 9, which is carried bv arms 15 pivoted on a rock-shaft 16 mounted in rigid arms 18. The winding - shaft 9 is rotated through gears 32, 31, 28, the gear 28 being loose on the rockshaft 16, and the gears 32, 31 being carried by the pivoted arms 15. Another gear-wheel 27, also loose on the rock-shaft 16 and separated from the gear-wheel 28 by friction disks 29, of which the tension can be adjusted by a spring 30 and a nut 100, engages with a further gearwheel 26 fast on the shaft 25 of the feed-roller 10, which is driven by a gear-wheel 24 from fast and loose pulleys 22, 21. As the winding- pulley 9 becomes filled with web material, its increasing diameter, through the slip device 29, causes its rotation to decrease, to take up the web material at the constant rate of feed. A counterbalance weight 102, adjustable by a nut 103 on a rod 101 fixed to the rocking-shaft 16. automatically relieves the feeding-roller 10 of any increase of pressure due to the accumulation of web material on the winding-roller 9. The arms 15, with the winding-roller 9, may be held at various heights by means of a ratchetwheel 52 fixed to the bracket 18 round the rockshaft 16, and a pawl 51 carried by an extension 50 of the arms 15 and operated from a handle 54 by connecting-rods 57, 56. To hold the winding-roller 9 in tension against the feedroller 10, a wheel 33, loose on the rock-shaft 16 and fast to the main framework 18 by a connecting-arm 75, carries a brake band 34 having its ends, of which the end 36 is adjustable, secured to one of the arms 15. To remove the winding-rollers 9 quickly when filled, one end 45 thereof is connected to its driving-shaft 40 by a sliding sleeve 43 having a central web 44 engaging the correspondingly slotted ends of the roller 9 and shaft 40. A spring 46 holds the sleeve 43 in position, and a screw 47 limits the sliding of the sleeve.
