Abstract: 278,301. Marks, E. C. R., (Cameron Machine Co.). June 30, 1926. Winding webs.-A web-winding apparatus, particularly for winding paper as it is delivered from a palper-making machine, comprises two winding drums spaced apart and means for moving the winding shaft, during the winding action, first over the surface of one drum and then into the valley between the drums Means may be provided to wind a certain amount of web upon the winding shaft before it is brought into engagement with the first drum. In one form,. Fig. 1, the web 39 passes round one drum 10 of a pair of winding drums 10, 11, to a winding shaft 19 which, during the initial portion of the winding of the roll, is supported out of contact with drum 10 and in engagement with a winding-roller 14 driven by a belt 15. The shaft 19 is carried in blocks 21 mounted in open slots 20 in arms 17 mounted on pivots 18 and normally resting against stops 24. The blocks 21 are a loose fit in the slots and are prevented from dropping to the bottom of the slots by engaging shoulders 25 on one side 32 of the slots. When the desired amount of material has been wound, the arms 17 are swung about their pivots 18 until the roll rests upon both drums in the position 79<a>. During this movement the blocks leave the shoulders 25 and slide on the opposite sides 23 of the slots. As the material accumulates, the blocks 21 leave the slots 20 and the arms 17 are then returned to receive a new winding shaft. As the roll increases in diameter the blocks enter guides 29 on arms 27 mounted on pivots 28. The arms 27, 17 have gear sectors 34, 33 connected by a gear 35 and one of the arms 27 has a gear sector 36 engaged by a pinion 37 on a shaft carrying a hand-wheel 38. When the roll has reached the desired size, the web is severed and the new end attached to the new shaft 19 to start the winding of a new roll and the wheel 38 is then operated to swing the arms 27 to the left to carry the shaft 19 of the full roll into engagement with supporting rails 30. On further movement of the arms, the blocks 21 leave the guides 29 and the roll finally rests against a latch 31. Simultaneously with this movement, the new roll is carried by the arms 17 into the main winding position. Feeding belts 40 conduct the web towards the drum 10 and pivoted fingers 43 operated by a hand-lever 45 are provided to raise the free end of the web into contact with the drum 10 In another form, Fig. 3, the pivoted arms 27 are replaced by arms 27a sliding through guides on the arms 17 and formed as racks engaging pinions 55 on a shaft 56 journaled in the arms 17 and provided with a hand-wheel 57. The arms 17 are operated by a hand-wheel 50 and pinion 51 engaging a quadrant 52. During the main winding operation, the blocks 21 are held in the upper ends of the arms 27<a> by latches 59 and the arms are consequently gradually raised. Upon completion of the operation and after the web has been severed and connected to the new shaft, the hand-wheel 50 is operated to bring the new roll into engagement with the drum 10 and the full roll on to the drum 11, the movement being de termined by the engagement of the arms 27<a> with adjustable stops 60. The arms 27<a> are then raised to lift the full roll clear of the drum 11 and the stops 60 adjusted to allow the arms 17<a> to be further turned to bring the full roll above the table 32. When the roll has stopped rotating, the stops 60 are further adjusted to allow the new roll to be moved completely into the main winding position, and the full roll to be deposited upon the table 32. The arms 27a are then lowered, and, when the bearing blocks 21 are clear of the arms 17a, these arms are returned to their initial position by operating the hand-wheel 50. In a third form, Fig. 6, the pivoted arms 17 are replaced by horizontally sliding arms 17b formed with racks 62 operated by pinions 63 and a hand-wheel 64. After the shaft 19 has been transferred to the valley between the drums 10, 11, the blocks 21 are engaged by jaws 67 carried by slides 66 mounted on guides 65. When the roll is completed, it is removed by a tackle engaging eyes 70 on the blocks 21. Specification 278,083 is referred to.
