An above-ground pool wall assembly apparatus is disclosed which allows the single handed mounting of the pool wall along the pool wall bottom rail. The rolled up pool wall is mounted on a turntable and kept upright by a plurality of retainer posts. As the wall is unreeled a series of guide posts help separate the unreeled portion of the wall from the roll and guide the wall into position on the bottom rail. As the pool wall is progressively mounted along the bottom rail, the apparatus can be kept in the proper position by wheeling the apparatus around the bottom rail in coordination with the progress of the installation.

A medium processing device includes a medium storage portion configured to stack sheet-shaped media to store the sheet-shaped media, a first pressurizing member configured to pressurize the sheet-shaped media stored in the medium storage portion, and a second pressurizing member configured to pressurize the sheet-shaped media in cooperation with the first pressurizing member when a stacking thickness of the sheet-shaped media stored in the medium storage portion is equal to or greater than a predetermined thickness.

Embodiments of a system and method for shingulating, singulating, and synchronizing articles in an article feeder system are disclosed. The article feeder system may include a shingulating device configured to receive a stack of articles and to produce a positively lapped stack of articles, a plurality of picking devices configured to pick one or more articles from the positively lapped stack of articles and to produce one or more singulated articles, and one or more synchronization devices configured to deliver the one or more singulated articles to one or more sorter windows.

An adjustment method for adjusting the heights of the nipping belts in a transport conveyor that moves flat articles in series and on edge, so that a transport height is substantially constant for the flat articles. The method causes the conveyor to operate empty in such a manner that the nipping belts of heights that are to be adjusted run without any flat article in the conveyor, emits two parallel and superposed light beams towards a belt of height to be adjusted, spaced apart by a certain distance equal to the width of the belt between the two opposite edges of the belt to be adjusted, the light beams emitted from a portable tool, and manipulate a tensioner adjusting the belt so as to move the belt heightwise while it is running empty until the two light beams intersect respective ones of the two opposite edges of the belt.

A system for gathering one or more mail items. The system includes a first gathering mechanism configured to press against a first of the mail or other articles, wherein the first gathering mechanism is configured to expand from a compact state to an expanded state. The area of surface contact between a first one of the one or more mail items and the first gathering mechanism increases when the first holder mechanism is in the expanded state.

According to one embodiment, a delivery accumulating apparatus includes a collection base which is capable of accumulating a plurality of deliveries to be sequentially overlapped in a standing state in an accumulating direction on a surface thereof; an accumulating paddle which is capable of supporting a plurality of the deliveries accumulated on the collection base from an opposite direction of the accumulating direction, the accumulation paddle being arranged from above the collection base so that evacuation is possible; and an accommodation box which is arranged below the collection base, and is capable of accommodating a plurality of the deliveries.

A separation/collection device is provided in a paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The separation/collection device separates and collects the conveyance subsidiary body and the paper sheet at an ending portion of a conveyance path. The separation/collection device includes a separation unit that passes the paper sheet pushed and conveyed by the conveyance subsidiary body, in a downstream direction, and that stops the conveyance subsidiary body by contacting the conveyance subsidiary body with the separation unit, a tubular path part that receives the paper sheet output from the separation unit, and a rib provided on an inner wall of the path part.

The method causes the conveyor to operate empty in such a manner that the nipping belts of heights that are to be adjusted run without any flat article in the conveyor, emits two parallel and superposed light beams towards a belt of height to be adjusted, spaced apart by a certain distance equal to the width of the belt between the two opposite edges of the belt to be adjusted, the light beams emitted from a portable tool, and manipulate a tensioner adjusting the belt so as to move the belt heightwise while it is running empty until the two light beams intersect respective ones of the two opposite edges of the belt.

Embodiments of a system and method for shingulating, singulating, and synchronizing articles in an article feeder system are disclosed. The article feeder system may include a shingulating device configured to receive a stack of articles and to produce a positively lapped stack of articles, a plurality of picking devices configured to pick one or more articles from the positively lapped stack of articles and to produce one or more singulated articles, and one or more synchronization devices configured to deliver the one or more singulated articles to one or more sorter windows.

A paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The paper sheet conveyance device includes an air volume adjustment unit that adjusts a strength of the airstream according to a position of the conveyance subsidiary body moving in the conveyance path.
