摘要:
A winding apparatus for and method of manufacturing helically wound tubular structures (116) includes: a rotating inner faceplate (74) upon which are mounted a forming station for forming a supply of strip material before it is wound into a desired structure; a plurality of inner supports in the form of inner support rollers (110) mounted for radial displacement and rotation about an axis; an outer faceplate (118) having a plurality of outer support rollers (92) mounted for radial displacement and rotation about an axis. In operation, the inner support rollers act to support an inner portion S1 of strip material wound thereon whilst allowing it to be supplied from an inner diameter thereof to said forming station and the outer support rollers (92) act to support an outer portion S2 of said strip. The inner support rollers (110) and outer support rollers (92) are adapted to move radially to maintain support of said strip material as it is consumed.

A rolled sheet-material supply handling-system that comprises a drawing device that can be configured to draw sheet material from a supply station and a stabilizer at the supply station. The stabilizer can define a generally tubular roll-receiving space in which a roll of the sheet material can be received and can have a support surface that can define an axial opening leading from the roll-receiving space to receive the sheet material drawn therefrom by the drawing device. The support surface can be sufficiently extensive to stabilize the outer layer of a roll against collapsing when the remainder of the roll has been extracted from the axial opening.

A winding apparatus for and method of manufacturing helically wound tubular structures (116) includes a rotating inner faceplate (74) upon which are mounted a forming station for forming a supply of strip material before it is wound into a desired structure and a plurality of inner supports in the form of rollers (110) mounted for rotation about an axis and with said inner faceplate and a plurality of outer driven rollers (92) provided on an outer faceplate (118). The inner rollers (110) are mounted for radial movement relative to the inner faceplate (74). In operation, the inner rollers (110) act to support an inner portion S1 of strip material wound thereon whilst allowing it to be supplied from an inner diameter thereof to said forming station and the outer rollers (92) act to support an outer portion S2 of said strip. Said outer rollers are driven as and when necessary to transfer material to the inner portion S1 and the radial position of the inner rollers increases as strip material is consumed from an inner diameter, thereby to maintain support of the strip supply regardless of the amount that has been consumed.

A material dispenser having a dispensing member configured to dispense a line of the material along a path in a downstream direction, and a cutting member having a cutting edge extending generally downstream with respect to the path. The cutting member having a convex shape across the path, such that the cutting edge engages and sequentially initiates cuts through the line of material when the line of material is pulled against the cutting member, thereby minimize cutting forces.

Die Erfindung betrifft eine Vorrichtung zur Aufrechterhaltung einer konstanten Zugspannung auf eine Materialbahn, insbesondere auf eine in einem Etikettiergerät (E) verwendete Etikettenbahn, die enthält: eine ortsfeste Drehachseneinrichtung (30) mit einer geometrischen Drehachse (M) und eine aus einer Ausgangsstellung um die Drehachse (M) der Drehachseneinrichtung (30) drehbare Zugspannungsausgleichseinrichtung (40), die eine Krafteinheit (60) aufweist, welche eine der Drehbewegung der Zugspannungsausgleichseinrichtung (40) aus der Ausgangsstellung entgegenwirkende Kraft auf die Zugspannungsausgleichseinrichtung (40) ausübt. Weiterhin ist vorgesehen, dass die Kraft der Krafteinheit (60) eine an der Zugspannungsausgleichseinrichtung (40) an einem Kraftangriffspunkt (65) mit einem radialen Abstand zu der Drehachse (M) der Drehachseneinrichtung (30) angreifende, linear wirkende Kraft ist.

A double-wound center-feed roll (1) is disclosed which is formed from at least two webs (2, 3) each having lines of weakness (4) which allow the webs to be separated into a plurality of sheets. The lines of weakness of one web are offset from those of the other such that in use the sheets can be dispensed singly from alternate webs. A first portion of the webs at the center of the roll is lightly bonded together while a second portion of the webs on the outside of the roll remains unbonded. The center-feed roll of the present invention reduces the occurrence of both web orientation reversal and streaming dispensing problems.

A method of deploying a containment boom is provided whereby an elongated material such as a sheet, yam, or yarn bundle, is formed into a roll and the material is pulled from the interior of the roll to create a helical structure. A pull rope is threaded through the interior of the roll and is deployed along with the material, such that the material is wrapped around the pull rope. The pull rope prevents the boom from stretching and distorting the helical structure formed by the material, as well as preventing the material from self-wringing. Multiple rolls of material may be provided in a single boom package arranged in coaxial alignment. When the materials are connected in parallel, they are integrated into a single boom having concentrically wrapped materials, thereby providing for greater stability and functionality.

A dunnage system (100) may include a converting station (114) including a converter (146) configured for pulling in a stream of sheet material and converting the material into dunnage, and an inlet guide (144) having an inlet surface that is coiled such that first and second ends of the inlet surface are discontinuous with each other to define a gap (158) therebetween, the inlet surface configured to channel the sheet material into the converter. A cutter (18) for a dunnage system (10) may include a blade (72) with first and second phases (221, 223) of serrations that are coextensive over at least a portion of the blade, the first phase providing cutting serrations for cutting the dunnage, and the second phase comprising ledges for focusing the cutting and preventing or reducing bunching of the dunnage towards a side of the blade. A method of converting dunnage may also be provided.

In operation, the inner rollers act to support an inner portion S1 of strip material wound thereon whilst allowing it to be supplied from an inner diameter thereof to said forming station and the outer rollers (92) act to support an outer portion S2 of said strip. Said outer rollers are driven as and when necessary to transfer material to the inner portion S1.

An apparatus (50) for and method of manufacturing helically wound tubular structures (116) includes coaxial rotating face plates (74, 89, 97), capable of rotation at different angular speeds. A plurality of forming rollers (76) and diameter defining rollers (78) are mounted on the inner faceplate (74, 89), which, in operation, cause a strip material (80) to be plastically deformed into a helical winding which may be lain down in abutting or self -overlapping relationship to form said tubular structure (116). A plurality of support rollers are mounted in a circle on the inner faceplate (74, 89) at a distance from the axis exceeding that of the outermost forming roller and serve to support the stock of strip material.
