Device for processing of flat elements and conveyor belt for use in such a device
A device for processing of flat elements, especially for the processing of paper blanks, is described. This device comprises a conveyor belt (25) that is guided over a first roller (12a) and a second roller (12b), said conveyor belt being made of metal and being permeable to air, wherein its upper section forms the transport section (25a) and its lower section forms the return section (25b), and a vacuum generator being located under the upper section of the conveyor belt. A laser (30) for cutting the flat elements is located above the transport section (25a). In order to achieve an improved flatness and an increased durability, the conveyor belt (25) consists of an expanded metal.
BELT CONVEYOR SYSTEM COMPRISING A MESH BELT AND A SHEET CONVEYOR SYSTEM FOR CONVEYING SHEETS IN A REPROGRAPHIC APPARATUS
Belt conveyor system comprising: an endless mesh belt, the belt having a mesh structure and having edge areas at the lateral sides, a drive mechanism drivable by a drive motor to rotate the belt, and a steering roller for steering the lateral position of the belt, wherein an edge area comprises a band running substantially parallel to the lateral sides, the band comprising an elastic filler being provided inside the mesh structure, the elastic filler being discernible from the mesh structure, and wherein the belt conveyor system further comprises a band position detector for detecting the lateral position of the band.
SHEET CONVEYING SYSTEM
A sheet conveying system includes an upstream conveyor section having an endless first conveyor belt movable in a first conveying direction x and extending in a first lateral direction z, the first conveying direction x and the first lateral direction z defining a first conveying plane xz; and a downstream conveyor section having an endless second conveyor belt that adjoins the first conveyor belt and is movable in a second conveying direction x′ and extends in a second lateral direction z′, the second conveying direction x′ and the second lateral direction z′ defining a second conveying plane x′z′. The conveyor sections are adapted to hold the sheets slip-free on the first and second conveyor belts. The second conveyor belt has a shear compliance in the second conveying plane x′z′ that is larger than the shear compliance of the first conveyor belt in the first conveying plane xz.
Reel-up for winding a paper web into a roll and a method of winding a paper web to form a roll
The invention relates to a reel-up (2) for receiving and winding into a roll (3) a paper web (W) that arrives from a drying cylinder (17) in a paper making machine (1). The reel-up (2) comprises a rotatably mounted reel spool (4) onto which a paper web (W) can be wound to create a paper roll (3) of increasing diameter and an endless flexible belt (5) mounted for rotation along a predetermined path of travel such that the flexible belt (5) forms a loop. The flexible belt (5) is positioned adjacent to the reel spool (4) to engage the paper web (W) against the reel spool (4) during winding such that the flexible belt (5) is deflected from the predetermined path of travel. According to the invention, the endless flexible belt (5) comprises electrically conductive material such that static electricity in the flexible belt (5) is dissipated away from the flexible belt (5). The invention also relates to a paper making machine in which the inventive reel-up is used and to a method of winding a paper web.
Transport device for paper, and paper processing device
Described is a transport device for paper which includes a metal conveyor belt through which air can flow and which is guided over at least two rollers, with the upper section of the belt forming the transport section and its lower section forming the returning section. A vacuum generator is arranged below the upper section. The conveyor belt is a metal mesh so as to be easy to produce and install.
