Abstract: A spool configured to support a roll of material. The spool comprises an arbor, a first flange, and a second flange. The first flange includes a first plurality of flange panels that are rotatably connected to respective arbor panels of the arbor at a first arbor edge of the arbor. The second flange is connected to a second arbor edge of the arbor. The first flange is configured to transition between a retention configuration and an open configuration. In the retention configuration, the roll of material is substantially prevented from removal from the arbor along an arbor axis by the first and second flanges. In the open configuration, the roll of material is removable from the arbor and receivable on the arbor in the arbor direction.

Abstract: The present invention relates to a device for handling a number of sleeves, preferably paper sleeves, before, during and after rolling up of a paper web each thereon, at least one insert sleeve bent from a rigid material web and having a length substantially corresponding to the total length of the rolls being inserted in the rolls for simultaneous handling thereof, wherein the insert sleeve is polygonal, e.g. triangular, rectangular, etc.

Abstract: A one-piece reel arrangement formed of a substantially quadrangle planar sheet is disclosed. The arrangement comprises longitudinal fold lines (A), transverse fold lines (B) and secondary transverse fold lines (E) neighboring to each of said transverse fold lines (B). Said fold lines (A, B, E) are formed by means of weakening the planar sheet material with perforations, incisions or semi-cut lines; wherein aforementioned fold lines (A, B, E) together form periodically repeating fragments along the longitudinal direction of the sheet. These fragments are adapted to be harmonically folded so that both longitudinal ends (4) are overlapped and attached to each other, and that reel body (3) and support legs (1) are formed by such folding.

Abstract: A mandrel and the blank from which the mandrel is formed is constructed so as to enable shipment in flat form to a manufacturer of material, e.g., fabric, who, in turn, assembles the mandrel and uses such to wind material thereon to form a fabric bolt. The blank is easily and entirely set up by simple folding procedures.

Abstract: [Object] It is intended to provide a spool capable of winding and retaining a thread-like substance without causing a winding curling. [Solving Means] This spool 11 has a base plate 14, thread retaining members 15 and 16, and auxiliary plates 17 and 18. The base plate 14 is made from a resin, paper, or the like and in the form of an elongated rectangle. The base plate 14 is folded at a central portion 21. The thread retaining members 15 and 16 are provided on opposite ends of the base plate 14. The auxiliary plates 17 and 18 are fixed to the thread retaining members 15 and 16 to form flanges. Ends of the auxiliary plates 17 and 18 are fixed to the base plate 14.

Abstract: A holder for wire material is disclosed. The holder includes a unitary body having interconnected and substantially planar expanses each having a discrete opening configured to receive and support a portion of the wire material as the wire material is wrapped around the interconnected and substantially planar expanses.

Abstract: A filter material take-up product and a paper winding core, which are free from secondary-contamination by an outgas while being transported or stocked. Irrespective of its application such as building air conditioner, an air cleaner or a semi-conductor factory, the amount of the outgas to be generated from the filter take-up product for the air filter can be kept at a negligible level. The filter take-up product for the air filter is produced by coating and wrapping the filter material for the air filter, as wound on the winding core, with a film wrapping material which is so made of phenolic compounds, carboxylate esters, phosphate ester or cyclic siloxance as to have an outgas generation in an amount of 100 ng/g or less by the dynamic head space method.

Abstract: A bobbin (1) of plastic has a cylinder (2) and, formed integrally therewith, circumferential end flanges (3) and is made of a U-shaped channel. Each end flange (3) consists of a plurality of spaced-apart, essentially radial flange elements (4) which are distributed along the circumference of the cylinder (2). In a method of manufacturing such a bobbin, a U-shaped channel is made by injection moulding. The U shaped channel is given such a shape that its side walls consist of a plurality of spaced-apart wall elements which are distributed along the length of the channel. The channel is bent to form the cylinder (2) and its ends are connected with each other in this bent position.

Abstract: A pair of flanges (12, 12) which have through-holes (17) for a rotating shaft, and a shaft part which connects the central parts of these flanges (12, 12) at a specified spacing, are formed from cardboard plates; furthermore, the above-mentioned shaft part is formed so that this shaft part is foldable. For example, flaps (13) which extend in the radial direction, and which have base ends (13a) on the side of the central part of the corresponding flange (12) are formed by stamping in each of the pair of flanges (12, 12) and slits (14) which extend in the circumferential direction of each flange (12) are formed on a circle that is concentric with the flange (12), and which includes the base ends (13a) of the flaps (13). The flaps (13) of the respective flanges (12) are pulled into upright positions, and the projecting parts (13b) of the flaps (13) of one of the flanges (12) are inserted into the slits (14) of the other flange (12), thus fastening the flanges (12) to each other, so that a reel (11) is formed.

Abstract: An improved electrode assembly for batteries and the like including a central mandrel configured to exert a resilient outward force on a multilayer web wound around the mandrel. The multilayer web includes a positive electrode layer, a negative electrode layer, and a separator layer separating the positive and negative layers. The resilient outward force acts to maintain the tightness of the web roll, thus lowering electrical resistance and enhancing battery cycle life. The mandrel is preferably formed of sheet metal configured to define an S-shape having a central section and first and second resilient leaves extending therefrom. The leaves preferably define substantially planar areas for bearing against an inner turn of the web roll to exert a resilient outward force thereagainst.

Abstract: A one-piece reel blank comprising a single piece of cardboard material, or other relatively rigid but foldable thin sheet material, which is cut to form a center panel, a pair of wall panels joined, and a pair of flaps. The center panel is preferably generally rectangular in shape with a pair of first fold lines and a pair of first lateral edges. The wall panels are respectively joined to opposite longitudinal sides of the center panel along substantially parallel second fold lines. Each second fold line has a length that is preferably less than that of the first fold line. A flap is joined to an adjacent wall panel along a third fold line opposite a fold line and substantially parallel thereto. Each flap is generally rectangular in shape and has a longitudinal fourth fold line having a central perforated or scored portion joining slit end portions, respectively terminating at lateral edges.

Abstract: A free standing paper towel dispensing apparatus (10) including a free standing support unit (11) having a generally rectangular base member (20) provided with a rectangular shaped central recess (21) which has a centrally disposed elongated support post element (23) that is dimensioned to be received in the cardboard tube (102) core of the roll of paper towels. A decorative cover unit (12) is dimensioned to receive a roll of paper towels (100) and includes an elongated dispensing container member (30) having an elongated dispensing slot (37), a closed upper end (31) and a lower end (32) provided with a stiffening block element (34) and a central aperture (33′) dimensioned to receive the support post element (23). The stiffening block element (34) prevents the movement of the lower end (32) of the dispensing container member (30) relative to the recess (21) in the base member (20), as well as retards the rotational movement of the roll of paper towels (100) within the dispensing container member (30).
