In another embodiment, the grooves are inclined to the vertical such that they contact the inner edge at right angles to the relative motion. In a further embodiment, the grooves are inclined generally parallel to the relative motion.

The hanger may employ a carrier supporting a plurality of gripper assemblies oriented in a spaced relationship with one another and having means by which the orientation of each of the gripper assemblies may be changed.
Abstract: A screw conveyor for conveying containers such as bottles and cans is arranged adjacent a guide rail which restrains the containers to stay in the groove of the screw until they are discharged, this being known per se. The angles for the screw conveyor and guide rail are adjustable to assure guidance of the center points of containers of any size along the same straight line without relying on inserting test containers. The guide rail is supporting on a transversely movable carriage and is pivotable thereon. The undriven end of the screw is supported on a member which is movable by a small amount. Stop elements such as bolts having different lengths are mounted in groups on a slidable member to enable positioning concurrently a stop element for the screw conveyor and a stop element for the guide rail pertaining to a particular container size and the stop elements react against stops on the carriage and the screw conveyor support member.
Abstract: A fuser belt for a reproduction machine is disclosed. The belt may have one of several configurations which all include ridges and interstices on the outer surface which contacts the print media. These interstices are formed between regularly spaced ridges, between randomly spaced particles, between knit threads. These interstices allow the free escape of steam from the media during high-temperature fusing of the reproduction process. As the steam escapes freely, the steam does not accumulate in the media causing media deformations and copy quality deterioration. Additionally, media handling is improved because the ridges and interstices reduce the unwanted but unavoidable introduction of thermal energy into the copy media.
Abstract: A non-contact article feeder takes randomly spaced articles and places these articles in proper spacing and timing for transfer to a wrapping machine without the use of tie downs or guide rails. A plurality of flat belt conveyors connected in series open or close gaps between adjacent articles and deliver the articles at proper phase and proper velocity to flights of a conveyor of a wrapping machine. A computer monitors the articles to provide synchronization of individual conveyor belts and between the feeder and the wrapping machine.

Abstract: An apparatus for transporting cops and cop tubes includes a plurality of circular-disk-type carriers having two opposite sides. Spindle bearings each have a bearing portion penetrating and protruding beyond a respective one of the carriers toward one of the opposite sides of a respective one of the carriers. Spool spindles each are rotatably supported in and protrude beyond a respective one of the bearings toward another of the opposite sides of a respective one of the carriers for carrying a cop or a tube. The carriers have substantially planar lower surfaces each surrounding a respective one of the protruding bearing portions. A transport apparatus movable in a given transport direction has a surface operatively connected to one of the opposite sides of each of the carriers. Another of the opposite sides of each of the carriers is slidingly guided in a guide rail.
