A controller controls the operation of the shafts and the actuators to selectively and individually control the location of each end of each belt assembly relative to one another and to a centerline of the conveyor.

The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method. Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

A transport device includes a first belt member movably stretched, a second belt member, a first roller, a second roller, a third roller, a fourth roller, a fifth roller, and a sixth roller. The second belt member is in contact with the first belt member to form a contact portion in cooperation with the first belt member. The second belt member is movably stretched. The first roller stretches the first belt member and is capable of adjusting a tilt in a longitudinal direction of the first roller. The second roller stretches the second belt member and is capable of adjusting a tilt in a longitudinal direction of the second roller. The third roller stretches the first belt member and is located adjacent to the first roller and upstream of the first roller in a movement direction of the first belt member. The fourth roller stretches the first belt member and is located adjacent to the first roller and downstream of the first roller in the movement direction of the first belt member. The fifth roller stretches the second belt member and is located adjacent to the second roller and upstream of the second roller in a movement direction of the second belt member. The sixth roller stretches the second belt member and is located adjacent to the second roller and downstream of the second roller in the movement direction of the second belt member. The third roller, the fourth roller, the fifth roller, and the sixth roller each have a uniform diameter in a longitudinal direction of the roller, and are disposed at positions other than the contact portion.

According to an embodiment of a tension maintaining device of a media transport belt, a device for maintaining tension of a belt to ensure a gripping force of the belt for gripping and transporting bundled media, in which a plurality of pieces of media are stacked, includes a rotation shaft; a link member coupled to the rotation shaft while having a predetermined length in a direction parallel to the longitudinal direction of the belt, and provided to be rotatable about the rotation shaft in response to a change in the number of pieces of the bundled media in contact with the belt; a first roller rotatably coupled to a first roller shaft provided at one end of the link member and maintained in contact with the belt; and a second roller rotatably coupled to a second roller shaft provided at the other end of the link member and maintained in contact with the belt.

A sheet feeder especially designed for use in the food and pharmaceutical industries is constructed in a hygienic manner and with suitable materials to permit rapid and effective cleaning and sanitizing thereof. Flexible, liquid impermeable bellows are mounted to the feeder housings in surrounding relation to the apertures through which the machine's several rotary shafts enter the housings. The bellows support bearing isolators that not only seal the housings from fluid entry, but because the bellows can flex, they also permit shaft spacings to be adjusted to adapt the machine to sheets of differing thicknesses and to set infeed belt tension. The sheet feeder's product input hopper and its discharge conveyor are designed to be easily detachable for cleaning in a dipping mode.

Method for unwinding web materials from two parent reels (1, 2), wherein a first parent reel (1) in a depletion phase is replaced by a second parent reel (2), wherein during said replacement a first and a second web material (N1, N2) are unwound from both parent reels, wherein before the completion of said replacement the first web material (N1) is joined to the second web material (N2) and then it is cut, wherein the joining of said web materials (N1, N2) is preceded by the insertion of the second web material in an area where the two web materials are joined, and during the step of inserting the second web material in said joining area the second web material is guided on a guide surface (41, 44) which guides it towards the joining area. In said insertion step, the second web material adheres pneumatically to guide surface.

A device for transporting notes of value comprises a first idler pulley mounted in the device and at least a second idler pulley mounted in the device, as well as an endless belt running around the idler pulleys, and a freely rotatable guide roller mounted in the device and having at least one connecting area for reception in a receiving opening of the device. The axis of rotation of the guide roller has in a first receiving position of the connecting area in the receiving opening a first orthogonal distance to a plane in which the axes of rotation of the idler pulleys run. The axis of rotation of the guide roller has in a second receiving position of the connecting area in the receiving opening a second orthogonal distance to the plane.

A recording medium conveyance device of an inkjet recording device includes a belt-form member, two conveyance rollers, a driver, a supporting board, a suction unit, and a guide roller. The recording medium is placed on the outer circumferential surface of the belt-form member. The belt-form member is pulled over the two conveyance rollers which cause the belt-form member to circulate. The driver causes at least one of the two conveyance rollers to rotate. The supporting board supports the inner circumferential surface of the belt-form member on a plane. The suction unit pulls the recording medium placed on the belt-form member to the outer circumferential surface of the belt-form member. The guide roller is arranged between at least one of the two conveyance rollers and the supporting board and supports the inner circumferential surface of the belt-form member.

A drive transmission device includes a chassis fixed to an apparatus main body and a driving roller that is driven by a driving source. A belt member transmits rotational force of the driving roller. A tension roller contacts the belt member to apply tension to the belt member. A support member supports the tension roller rotatably and is swingable about a rotational shaft of the chassis. A screw fixes the support member to the chassis at a predetermined position. A retaining member is able to be engaged with the chassis, in which the support member is arranged and fixed between a part of the retaining member and the chassis in an insertion direction of the screw.
