An elastic roller is capable of elastic deformation at low load, lightweight and low-cost, and the surface speed of the roller has been made stable. At a drawing showing the view from the side of pipe 2 and flange 3 which make up roller 1, roller 1 which has pipe 2 and flange 3 is supported by shaft 8 which is inserted therein along axis 8a of shaft 8, the situation being such that elastic deformation occurs upon being pressed downward by pressure P from pressure-applying body 11 above pipe. None of the four outermost ribs 7a disposed in outermost gap 6a between outermost ring 4a of flange 3 and middle ring 4b which is mutually adjacent thereto and toward the interior therefrom is present in the upper portion of pipe 2.

A post-processing device includes an output unit that outputs a medium; a stacking unit on which the medium that is output is stacked; and a blow-out unit that is disposed below the output unit and that blows gas toward the medium that is output, wherein an amount of the gas blown is adjusted in accordance with a type of the medium.

A working table for a reel-to-reel process includes: a supply reel configured to supply a workpiece; a collection reel configured to collect the workpiece after the workpiece is processed; a base on which the supply reel and the collection reel are installed; a processing workbench installed on the base to process the workpiece thereon; at least one balance adjuster installed on the base and configured to be moved according to weight variations of the supply reel and the collection reel; a balance drive unit configured to drive the at least one balance adjuster; and a controller configured to control the balance drive unit.

An apparatus for diverting and/or folding articles includes an infeed conveyor, an outfeed conveyor, and a diverter. The diverter is a non-contact, fluid emitting diverter, configured to emit a fluid jet to exhibit the diverting force on the impact zone of the article at a side of the article facing away from the outfeed entry. An angle of the average direction of the diverting force of the fluid jet with the outfeed path at the outfeed entry is in the range of 5° to 85°.

A line is disclosed for producing logs of web material provided with a system for controlling, in real time, one or more parameters of the logs produced by the line and for facilitating any corrective actions. The line includes a rewinder, a feed path for the logs from the rewinder towards at least one station arranged downstream of the rewinder; and a measurement station. The measurement station includes at least a measurement device for measuring at least one parameter of logs randomly selected from the feed path and held in the measurement station, for example a device for measuring the firmness of the logs. The measurement station further includes first transferring members for transferring selected logs from the feed path to the measurement station, and second transferring members for transferring selected logs from the measurement station to the feed path.

To provide a post-processor capable of executing alignment processing with high accuracy.

Configuring a post-processor including: a recording material loader on which a recording material conveyed through a conveyance path is loaded; an aligner that aligns the recording material in the recording material loader; a driver that moves the aligner; and a controller that receives information of a physical property value of the recording material acquired by a medium sensor and determines an operation parameter of alignment processing that drives the driver based on the information of the physical property value.
