Sheet conveying device and image forming apparatus incorporating the sheet conveying device
A sheet conveying device includes a conveying body, a pressing body, and an attracting device. The conveying body conveys a sheet. The pressing body presses the sheet to a circumferential surface of the conveying body at an upstream side from an operation start position at which an operation with respect to the sheet starts, in a sheet conveying direction. The attracting device sucks and attracts the sheet onto the conveying body. The attracting device includes an attracting unit having an attracting region extending shorter than a distance between the pressing body and the operation start position. The attracting unit rotate together with the conveying body.
Medium transporting device and liquid jetting device
A medium transporting device and a liquid jetting device, which can suppress the lifting of both ends of a medium in a width direction of a medium and can suppress the occurrence of wrinkling of the medium, are provided. The medium transporting device includes a gripping unit that grips a leading end region of a medium, a medium supporting unit that has a first adsorption supporting unit which adsorbs and supports a trailing end region of the medium and a second adsorption supporting unit which adsorbs a non-end region of the medium and generates an adsorption pressure less than an adsorption pressure generated by the first adsorption supporting unit, a medium position moving unit that moves a position in a medium width direction in the medium width direction, and a medium transporting unit that transports the medium. Regarding the width direction, the first adsorption supporting unit has a length, which is obtained by adding a length twice a moving distance of the medium to a medium length, and a distance from a center position in the width direction to one end in the width direction is the same as a distance from the center position in the width direction to the other end in the width direction.

Transfer mechanism and bag supply apparatus
A transfer mechanism includes a main rotating member, a first driving unit, a support mechanism, a holding unit, a second driving unit and control unit and transfers a sheet member from a pickup position to a delivery position. The support mechanism is connected to the main rotating member and the holding unit. The control unit controls the second driving unit in such a manner that, when the sheet member is placed in at least one of the pickup position and the delivery position, a position of the holding unit is not substantially changed in a state where the main rotating member rotates around the rotational axis in the first rotation direction.

Apparatus and method for manufacturing absorptive article
An apparatus and method for manufacturing an absorptive article are capable of suppressing the occurrence of wrinkles in a constituent element of the absorbing article when transferring the constituent element to a downstream conveying device. A main suction pad that moves along a cylindrical or conical first virtual path surface receives a constituent element from an upstream conveying device, changes the orientation by 90° and conveys the constituent element to a second position. Sub-suction surfaces of the first and second sub-suction pads move around a second reference center line along a cylindrical or conical second virtual path surface centered on the second reference center line, while being aligned with each other with a space therebetween, suction end portions of the constituent element at the second position, and transfer the constituent element to the downstream conveying device at a third position.

Systems and methods for cutting or perforating a web material
Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.
