Abstract: The present invention relates to a powered roller bed with multiple rows of rollers, wherein two or more self-powered rollers are provided on each row along the bed. The rollers are preferably powered by electromagnetic motors having a stationary shaft and a rotating cylinder thereon so that each one can be independently controlled and operated. The present invention preferably provides a means of installing and removing each roller by hand without the aid of tools.

Abstract: A sound abatement method includes applying a sound abating material to at least one area of at least one component of the moving trolley. A sound abatement conveyor trolley includes a trolley body having at least one wheel for traveling in a track and one or more component cooperatively associated with the trolley body, which the components each include a sound abating material applied to the area for sound abatement. An element used in a conveyor trolley includes at least one area and a sound abating material applied to the area for sound abatement.

Abstract: A conveyor switch for a conveyor track comprising a tubular linear induction motor as the switch drive. A switch tongue is adapted to be pivoted between first and second positions on the conveyor track and has a driving arm extending from one end thereof. The switch drive is operatively connected to the driving arm for driving the switch tongue, wherein the switch tongue is adapted to direct a moving conveyor component between first and second paths of travel on the conveyor track. Various means are provided to account for the linear movement of the switch drive in relation to the arcuate movement of the switch tongue. The switch assembly is especially adapted for switches in power and free conveyor systems.

Abstract: A device is disclosed for storing a stream of a plurality of thin flexible objects, such as newspapers or similar printed materials, which is constructed from a number of generally parallel conveyor sections arranged in a number of vertical columns. The conveyor sections in each column are connected to one another by diverter belts located at the ends of the columns and the last conveyor section in one column is connected to the first conveyor section in an adjacent column by an offset transfer conveyor. In operation, a lapped stream of objects is fed into the input of the storage device travels in a serpentine manner along all of the interconnected conveyor sections in a first column, across the transfer conveyor to a second column where the process is repeated. The remaining columns are traversed in the same manner until the stream reaches the end of the last conveyor.
