A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

A vacuum wheel for transporting a substrate includes a fixed conduit that is connectable to a suction source. A vacuum surface on a circumference of the vacuum wheel includes vacuum openings that are distributed around the circumference, such that rotation of the wheel causes the vacuum openings to successively fluidically connect to the fixed conduit. When suction is applied to the fixed conduit, suction is applied to one or more of the vacuum openings that are currently fluidically connected to the fixed conduit. At least one contact surface on the circumference of the vacuum wheel is adjacent to, and extends outward beyond, the vacuum surface. When suction is applied to the vacuum openings, the substrate is drawn toward the vacuum surface so as to contact the contact surface without contacting the vacuum surface, creating a friction force that enables transport of the substrate when the wheel rotates.

A conveyance mechanism includes a lower conveyance guide below an inclined conveyance path having upward or downward inclinations with which a sheet material is to be conveyed, that guides a lower surface of the sheet material; an upper conveyance guide above the inclined conveyance path, that guides an upper surface of the sheet-shaped material, the upper conveyance guide being openable and closable about a rotation shaft, which is on a side of the inclined conveyance path in a direction of a width of the inclined conveyance path to extend along the inclined conveyance path; and a first urging member to urge a portion of the upper conveyance guide away from the rotation shaft in the direction of the width of the inclined conveyance path toward the rotation shaft, the portion of the upper conveyance guide being at an upper end of the upper conveyance guide in an inclined direction.

Maker machine to manufacture hygiene absorbent articles and having: a feeding line which feeds a continuous strip of impermeable material, which is intended to define a succession of sheets of impermeable material; and at least one operating unit which feeds a corresponding component of the hygiene absorbent articles to the sheets of impermeable material carried by the feeding line by way of an application device; the application device has at least one sucking pick-up head and a conveyor provided with an annular guide which is arranged in fixed position along an application path, a slide which supports the sucking pick-up head and is coupled to the guide so as to freely slide along the guide, and a linear electric motor, which has a stator that is arranged in a fixed position along the guide and a mobile slider which is electro-magnetically coupled to the stator so as to receive, from the stator a driving force and is rigidly connected to the slide.

In a sheet member inspection method for a sheet member conveying apparatus configured to convey a sheet member with a tension, the sheet member conveying apparatus includes: a first support roller placed on an upstream side in a conveying direction of the sheet member and configured to support conveyance of the sheet member; a second support roller placed on a downstream side relative to the first support roller in the conveying direction and configured to support the conveyance of the sheet member; and a magnetic-force detection sensor placed on the downstream side relative to the first support roller in the conveying direction. The sheet member inspection method includes: applying a magnetic force to the sheet member by the first support roller; and inspecting, by the magnetic-force detection sensor, whether a magnetic object exists in the sheet member to which the magnetic force is applied by the first support roller.

A paper sorting device includes: a stacking conveyor that receives continuously fed cut sheets to stack the cut sheets by sorting unit and that continuously conveys stacked cut sheets downstream on a unit-by-unit basis; and a stacker section arranged downstream of the stacking conveyor, capable of continuously stacking the stacked cut sheets conveyed from the stacking conveyor, at different positions on a placement surface.

A sheet transport device includes a pair of movable transport rollers capable of transporting a sheet while holding the sheet and capable of moving in an axial direction crossing a transportation direction; pairs of first transport rollers disposed upstream from the pair of movable transport rollers in the transportation direction while being spaced apart from each other to transport the sheet while holding the sheet; and pairs of transport guides disposed to define sheet transport spaces between the pair of movable transport rollers and the pairs of first transport rollers and between the pairs of first transport rollers. When the pair of movable transport rollers is to be moved in the axial direction, at least one of the pairs of first transport rollers is displaced in the axial direction while holding a portion of the transported sheet.
