It is an object of the present invention to provide method for receiving sheets for a sheet supplying apparatus. The method includes converting an up and down motion of a tray to a rotational motion of a rotary member by a movement conversion mechanism, converting the rotational motion of the rotary member around a rotational axis to a linear motion of a cylindrical member parallel to the rotational axis by the rotary member and a cam and slider mechanism, and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by a compression spring.

A machine for making absorbent sanitary articles includes a device for feeding a continuous strip to a conveyor roller and to a device for cutting the strip into first and second pieces. A unit forms and applies at least a pair of first and second pieces, aligned and spaced by a distance (d), for each absorbent article A first and a second roller each comprising a plurality of units pick up and successively release of first and the second pieces. A plurality of concentric units rotating, independently of each other, about a shared axis of rotation, each carries at least one unit. A motor defines a respective law of motion for each of the units and a mechanism translates the units, between a position for picking up the pieces, at the conveyor roller, and a position for releasing the pieces, at the forming and applying unit.

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.

A sheet-transporting element includes suction openings for holding print sheets, longitudinal sliders including air passages, and transverse sliders including air passages. The longitudinal sliders and the transverse sliders are disposed in a cross-wise configuration and are movable into different positions corresponding to various sheet formats in the positions blocking selected ones of the suction openings.

A drum assembly for processing a moving web of material is disclosed. The drum assembly has an outer drum with an axis of rotation and a plurality of support members on which cut patches of the moving web of material are supported as the drum rotates together with said support members about said axis. A cam is disposed within the outer drum and the support members and the cam cooperate with each other as the outer drum rotates relative to the cam to move the support members in an axial direction to alter the spacing between cut web patches on said support members.

It is an object of the present invention to provide sheet supplying apparatus. The sheet supplying apparatus has a tray; a guide mechanism; a movement conversion mechanism; a rotary member; a cam and slider mechanism and a compression spring. The movement conversion mechanism converts an up and down motion of the tray to a rotational motion. The rotary member comprises a transmitted portion configured to receive a rotational motion converted from the up and down motion of the tray in cooperation with the movement conversion mechanism and a driven portion configured to receive a rotational driving force to lift the tray. The cam and slider mechanism converts the rotational motion of the rotary member to a linear motion of a linearly movable member. The compression spring elastically presses the linearly movable member of the cam and slider mechanism in the rotational axis direction to lift the tray.

A sheet processing device includes a first pressing unit that presses sheets with a first force, and a second pressing unit that presses the sheets with a second force larger than the first force after the sheets are pressed with the first force. The sheets are bound by the second force.

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.

A sheet conveyance apparatus is equipped with a first rotator, a second rotator conveying a sheet together with the first rotator, a cam member changing a position of the second rotator with respect to the first rotator, a drive unit rotating the cam member, and a load portion applying load on a rotation of the cam member. The load portion includes a contact member having a cam surface formed on a side surface in an axial direction of the cam member, an abutment member capable of abutting against the cam surface, and a biasing member biasing one of the contact member and the abutment member toward the other, a biasing force of the biasing member converted into a force, applying load to the rotating cam member, by the cam surface opposing to a rotating direction in which the cam member is driven by the drive unit.
