A clamping device (400) for gripping and clamping a flat material (12) extending along a material plane (11) includes clamping jaws (402). The clamping jaws include a first clamping jaw (404) and a second clamping jaw (406) extending parallel to a clamping axis (408). The first and/or second clamping jaws are pivotable about a clamping rotational axis (410) running parallel to the clamping axis between open and closed positions. The first clamping jaw has a first clamping surface (414) and the second clamping jaw has a second clamping surface (416). The first clamping jaw has a clamping element (418) projecting relative to the first clamping surface and the second clamping jaw has a clamping recess (420) that is set back from the second clamping surface. In the closed position, the clamping recess accommodates the clamping element so that the flat material is gripped and clamped simultaneously.

A roll-to-roll web processing system including a web supply roller operative for supplying web material, at least one upstream intermediate roller for receiving the web material from the web supply roller and directing the web material along at least a first web pathway portion, a processing subsystem arranged along at least a second web pathway portion, at least one downstream intermediate roller for receiving the web material from the processing subsystem and directing the web material along a third web pathway portion, and a web take up roller operative for taking up the web material, the first, second and third web pathway portions at least partially delimiting an internal volume interior of the at least one upstream intermediate roller, the processing subsystem and the at least one downstream intermediate roller and the web supply roller and the web take up roller being located in the internal volume.

Rewinder for the production of logs. A feeding element adapted to supply a paper web. A guide element adapted to guide sequentially several cores along a predetermined path between a station for feeding the cores and a winding station in which a predetermined amount of the web is wound on each core. A winding element adapted to wind the paper web on the cores in the winding station. The guide element includes a guide with a curved end section that ends in the winding station and in cooperation with the winding element, delimits a channel crossed by each core before reaching the winding station.

A dispenser for pillow napkins is provided that includes a carton having a bottom panel, opposite left and right panels extending vertically from the bottom panel, opposite front and back panels positioned between the left and right panels and extending vertically from the bottom panel, and a top panel extending parallel to the bottom panel. Left and right supports are positioned within a cavity of the carton. A plurality of pillow napkins are wound about a spool. The spool is positioned in the cavity such that the spool rotatably engages the left and right supports and the pillow napkins are spaced apart from the top and bottom panels. Methods of use are provided.

An auto splicing apparatus of roll to roll feeding equipment includes first and second supply rolls in which component fabric of a single layer is wound in roll form and the component fabric is unwound from the first supply roll or the second supply roll along a predetermined transfer path including a pair of feeding rollers that are disposed at upper and lower sides, respectively, of the transfer path; a first cutter assembly that is installed to perform a first vertical rotation based on the transfer path between the first supply roll and the feeding roller and including a first fabric cutter and a first fabric absorption portion; and a second cutter assembly that is installed to perform a second vertical rotation based on the transfer path between the second supply roll and the feeding roller and including a second fabric cutter and a second fabric absorption portion.

A slitter device includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism, a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials, and a drive control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the comparator.

A method of manufacturing a cleaning member includes a fiber bundle conveying step conveying a fiber bundle to a merging section, a nonwoven fabric conveying step conveying the nonwoven fabric strips to the merging section; a multilayer web forming step forming a multilayer web by overlaying the fiber bundle on the nonwoven fiber strips at the merging part; and a joining step joining the fiber bundle and the nonwoven fabric strips to each other in the multilayer web. In the fiber bundle conveying step, the fiber bundle is conveyed at a tension at which there is no width shrinkage in the fiber bundle, and in the multilayer web forming step, the multilayer web is formed by overlaying the fiber bundle on the nonwoven strips while applying a tension that does not cause width shrinkage in the fiber bundle.

A paper conveying mechanism includes an elastic urging member provided on each side surface of an upper guide. The urging member includes a projecting portion that projects toward a side guide forming each end of a paper conveying path. An outer width of the upper guide inclusive of the projecting portion is greater than an inner width of the side guides. When a printer cover is closed, the upper guide is urged by the urging member substantially to the center of the inner width of the side guides, thereby producing gaps of substantially equal size on both sides of the upper guide in the paper width direction.
