The present invention relates to a web film movement compensating device for a web film movement compensation between continuous forward movement section and intermittent forward movement section comprising two guide rollers (1, 2) rotating freely in stationary positions between a continuous driving device (5) and an intermittent driving device (6), two compensation rollers (3, 4) rotating freely on two respective pivoting arms (7, 8) oscillating about pivot shafts (11, 12), an elastic element (9) connected to one of the pivoting arms to actuate the corresponding compensation roller to move away from the guide rollers, and a movement transmission mechanism including lever arms and transmission rods (13, 14, 15) transmitting an oscillating movement from one of the pivoting arms (7, 8) to the other. A web film (50) moved by the driving devices is supported on the guide rollers (1, 2) and on the compensation rollers (3, 4) forming a meander.

A suction conveyor device comprising a suction arrangement having a suction side on which low pressure is generated, continuously rotating flexible conveying means made of flexible flat material having holes, an inner side enabling the conveying means to move along the suction side, and an outer side for receiving flat items in the active area of the suction side, where the conveying means moves in the transporting direction, the suction arrangement and the conveyor means designed with a transport path width in the active range perpendicular to the transporting direction. The conveying means includes continuously circulating individual, single-piece, flexible conveying means, both lateral edges thereof extending in the transporting direction at a distance from each other being at least the same as the total width of the transport path such that the individual, single-piece flexible conveyor means extend over the total width of the transport path.

In a paper sheet storing apparatus housed in a paper sheet handling apparatus, a storage part stores paper sheets. An ejection port ejects a paper sheet of the paper sheets stored in the storage part. A first roller is arranged near the ejection port, and is rotated in a predetermined direction by transmission of rotation caused by drive of a drive shaft so as to send out the paper sheet from the ejection port. A driven shaft is rotated in the predetermined direction following the rotation of the first roller. A second roller is arranged in a position farther from the ejection port than a first roller, and is rotated in the predetermined direction by transmission of rotation of the driven shaft so as to sequentially feed, to the first roller, the paper sheets from a paper sheet positioned in a lowest layer among the paper sheets.

A creel, such as may be used to supply fiberglass roving to a production process, includes an enclosure and a number of rotatable axles held within the enclosure. Each of the axles is of a shape and size to be inserted into a bobbin of roving. The creel also includes a drive mechanism coupled to each of the plurality of rotatable axles, the drive mechanism synchronizing the rotation of the axles. Bobbins of roving may be stacked on the axles and connected to provide continuous roving. As roving is drawn from the creel, the rate of rotation of the axles may be selected to counteract twisting of the roving that would otherwise result.

Disclosed is a festooner and a method for buffering a strip, the festooner having a first set of buffer rollers and a second set of buffer rollers, wherein the first set of buffer rollers and the second set of buffer rollers define a meandering first buffer path between them, wherein the festooner further includes a first endless drive element for driving the first set of buffer rollers and the second set of buffer rollers. The festooner further includes a third set of buffer rollers and a fourth set of buffer rollers coaxial to the first set of buffer rollers and the second set of buffer rollers, respectively, defining a meandering second buffer path between them. The festooner further includes a second endless drive element for driving the third set of buffer rollers and the fourth set of buffer rollers.

Disclosed is a festooner and a method for buffering a strip, wherein the festooner includes a first holder and a second holder which are oppositely movable towards and away from each other in a buffer direction to vary a buffer capacity of the festooner, and a first set of buffer rollers and a second set of buffer rollers held by the first holder and the second holder, respectively, wherein the first set of buffer rollers and the second set of buffer rollers define a meandering buffer path between them. The festooner further includes an endless drive element for driving each buffer roller, wherein the festooner further includes an overlength collector for collecting and paying out an overlength of the endless drive element.

A plurality of support rollers support a conveyor belt. A first transmission mechanism transmits a rotational force of a first motor to one of the plurality of support rollers. A second transmission mechanism transmits a rotational force of a second motor to one of the plurality of support rollers. A first control portion controls a first supply power supplied to the first motor in accordance with a difference between a speed detection value and a target speed. A second control portion controls a second supply power supplied to the second motor in accordance with one or both of conveyance information on a conveyance state of an object in a specific area and suction force information on a suction force of a suction fan. The second transmission mechanism transmits the rotational force at a greater reduction ratio than the first transmission mechanism.

A sheet feeding apparatus includes a sheet stacker to stack at least one sheet; a sheet feed roller disposed at one side of the sheet stacker and to feed a sheet fed from the sheet stacker; a multi-feed prevention roller disposed to face the sheet feed roller and to prevent multi-feed of the sheet fed from the sheet stacker; a magnetic torque limiter disposed coaxially with the multi-feed prevention roller; a hall sensor disposed at one side of the magnetic torque limiter and to detect rotation of the magnetic torque limiter; and a controller configured to rotate the sheet feed roller in a state in which the sheet feed roller and the multi-feed prevention roller are in contact with each other without a sheet and to identify a lifetime of the multi-feed prevention roller by using a signal output from the hall sensor.

A lifting system for inner yarn rails relates to the technical field of twisting and weaving equipment in factories, the system comprises an in-air conveying rail, and a carrier unit, wherein the in-air conveying rail is configured to convey the carrier unit, and the carrier unit is configured to carry a winding package; an inner yarn-carrier-lifting section is arranged on the in-air conveying rail, the inner yarn-carrier-lifting section is positioned on both sides of a twisting machine; when the inner yarn-carrier-lifting section rises, it communicates with the in-air conveying rail; when the inner yarn-carrier-lifting section descends, it approaches the position of a spindle bucket of the twisting machine. The winding packages delivered each time by one carrier unit can correspond to every spindle position of the twisting machine, dramatically improving the delivery efficiency of the winding packages.

A paper feeding device includes a pickup roller mechanism disposed at an entrance of a paper feeding path, and a separation mechanism disposed to a rear end of the pickup roller mechanism. The pickup roller mechanism includes a first pickup unit positioned at the entrance of the paper feeding path, a second pickup unit mounted to a rear end of the first pickup unit, and a third pickup unit disposed to a rear end of the second pickup unit. The second pickup unit includes a first driving gear. The third pickup unit includes a second driving gear, and a transmission belt looped around an outer periphery of the first driving gear and an outer periphery of the second driving gear.
