Abstract: A method and device for treating containers with at least two container treatment machines, between which a transport device for transporting the containers is arranged, where the transport device is divided into several transport sections, where the flow of containers is changed from containers of type A to containers of type B, where a separating device is activated once the first transport section has run empty of containers of type A, where containers of the type B are transported into the first transport section and backed up at the separating device, while containers of type A are transported from the second transport section to the second container treatment machine, and where the separating device is deactivated once the second transport section has run empty of containers of the type A, so that the containers of type B are transported through the second transport section to the second container treatment machine.

Abstract: The invention relates to a friction drive for force transmission, in particular for a transport conveying device, comprising a drive element (31) and an output element (34) and comprising a torque-limiting device (33), which acts therebetween and transmits a drive torque introduced by said drive element (31) up to a transmission torque, which can be set by means of the torque-limiting device (33), to the output element (34), and allows free running when a drive torque exceeds the set transmission torque, and which comprises at least one rolling bearing (41) having an inner race (42) and an outer race (46) and rolling bodies (45) arranged therebetween, and a clamping device (51), by means of which the inner race and the outer race of the at least one rolling bearing (41) of the torque-limiting device (33) can be displaced towards each other in an axial direction or can be clamped against each other in a radial direction and a transmission torque can be set.

Abstract: A system and method for coating substrates includes transporting rolls and a collecting container for collecting coating material.

Abstract: A conveyor assembly includes a series of rollers for conveying a product to one or more product operations. A pair of spaced apart side frames support the series of rollers spanning between the frames. A drive system is associated with one or more rollers of the series of rollers and includes a selectively inflatable bladder, an elastomeric sleeve and a moving belt, wherein inflation of the bladder pushes the moving belt against one or more of the rollers for their rotation. A brake system is associated with one or more of the series of rollers and includes a selectively inflatable bladder and a fixed elastomeric band, wherein inflation of the bladder pushes the fixed elastomeric band against one or more of the rollers for stopping its rotation.

Abstract: The transport device especially for transporting flat substrates through a coating installation comprises a plurality of transporting rolls, which are arranged transversely in relation to the transporting direction, and supporting rolls are also provided.

Abstract: A feed wheel includes a hub and a discontinuous tread removably fitted about the hub. At leading and trailing ends of the discontinuous tread are mateable non-planar female and male surfaces which interfit with one another and tend to interlock the tread ends together. The tread has locking lugs formed under leading and trailing ends and an intermediate segment of the tread which fit into holes configured and located in the hub complimentarily to the locking lugs. The holes and locking lugs are oriented relative to one another so as to enable the tread to be retained about the hub with the tread ends interlocked together during operation of the feed wheel.

Abstract: A roller conveyor belt driver system for a roller conveyor includes a closed loop belt having a continuous driving surface and a non-circular base and a plurality of pulleys which support and engage said non-circular base for at least partially laterally restraining the belt from rotation. A first group of pulleys are constructed and arranged to position the belt in non-orthogonal orientation with respect to the rollers of the conveyor for contacting one or more rollers with the driving surface of the belt. Optionally, the belt driver system includes a lateral restraint associated with a respective pulley of the first group of pulleys to urge the belt to remain engaged with the respective pulley to prevent twisting of the belt and, therefore, increase the life of the belt. For example, the lateral restraint may comprise a bearing which is positioned adjacent the respective pulley and which contacts the belt to maintain the belt in proper orientation in the pulley.

Abstract: A magnetic coupling assembly for selectively rotating rollers of a roller conveyor when the torque required to maintain this rotation does not exceed a predetermined threshold is described herein. The magnetic coupling is mounted to the side rail of a conveyor, below the conveyor rollers and include a driving portion rotatably mounted to the side rail and a driven portion rotatably mounted to the driving portion. Corresponding friction surfaces of the driving and driven portion are brought and maintained in contact via a magnet and an element made of magnetic material or another magnet. Means for varying the distance between the magnet and the element made of magnetic material are disclosed. The present invention is also concerned with means for simultaneously adjusting more than one coupling assembly and with means for detecting the rotation of conveyor rollers.

Abstract: The invention relates to a live roller conveyor comprising a plurality of rollers driven by friction drive from a main drive shaft wherein at least some of said rollers are driven from the main drive shaft through a secondary drive shaft and there being control means to vary the torque transmitted between the main drive shaft and the secondary drive shaft.

Abstract: A roller conveyor with a plurality of rollers (3, 6, 13) which are held in a frame (2), which rollers are assigned to several sections (4), and a drivable and brakable roller (13) is assigned to each section (4) which is coupled with the other rollers (3) of the same section (4). In order to enable a simple arrangement, it is provided that the drivable and brakeable rollers (13) are each held on a fixed axle (15) on which a drive roller (6) is also held and which can be coupled with the drivable and breakable roller (13) by way of an electromecanical clutch (18′, 23′), which roller on its part is provided with an electromechanical braking device (18, 23).
