Abstract: A filter apparatus and method utilize a filter element having a central winding frame and a length of fluted filter material wound about the frame with the flutes of the media oriented substantially longitudinally, to thereby provide for filtration of a flow of fluid passing axially through the filter element. The winding frame is a substantially open, truss-like structure, having a smooth outer periphery and an axially extending winding feature to facilitate pulling the media into intimate contact with the smooth outer periphery during fabrication of the filter element. A leading edge of the filter media is anchored to a leading edge of the frame by a length of tape.

Abstract: A package of flat material in a flat profile and a method for making the package. Flat material is wound around a core having hollow channels that are coupled by engagement with extruding pins from a member. The member is mounted on an axis that rotates, causing the member to rotate. The rotation winds the flat material onto the core. The final package of flat material has a flat profile, which may be a convenient shape for storage in small and confined places.

Abstract: A stretching device for filiform elements comprises a main body member (1) having ends, with one of the ends having a connection opening (2) and the opposite end of the plate member having a rotating mounting opening (3) in the rotating mounting opening there is a rotating part (6) having a command head (11) which forms a winding reel (7) for the wire to be stretched; mounted on the main body (1) is a slide mobile cramp (12). The winding to stretch the element is done by turning the command head (11). Once the suitable stretching has been achieved, the slide mobile cramp (12) is slided until said command head (11) is introduced into the cramp recess (15) formed by the cramp fork (14). Under these conditions, the rotating part (6) is fixed, keeping the tension on the filiform element.

Abstract: A skein support bow includes an elongated solid main section made of flexible material and has a length approximately equal to the length of a skein to be mounted thereon. Double hook members are located at each end of the elongated main section for engaging a corresponding loop end of the skein. An excrescence is integrally appending from the main section and forms a label hanger for receiving a label after the label is removed from the skein thereby making information on the label available after the skein is mounted to the bow.

Abstract: A film belt package which facilitates loading on support rollers while maintaining the belt protected within the package until loaded on the support rollers. This film belt loader package supports the film belt under tension and in a configuration which substantially replicates its configuration when located on such support rollers. The belt, on its tension support, is enclosed by a member which is adapted to engage such film belt for urging such film belt off of the tension support in order to load such belt on support rollers.

Abstract: A reel comprising spaced, parallel flanges between which is disposed a hub wherein the flanges comprise first and second outer side wall panels and the hub first and second longitudinal hub panels positioned between the first and second outer side wall panels at right angles thereto and reinforced panels disposed at the inner sides of the first and second outer side wall panels, said panels being so associated as to be formed of a single sheet of cardboard and to be folded to form a reel wherein the flanges of the reel are of no more than two ply thickness.

Abstract: Bobbin apparatus for releasing a connecting filament between a radiosonde and the sonde balloon in a controlled manner during the ascent thereof includes a longitudinally extending member adapted to be affixed to the balloon around which the filament is wound and having a transverse dimension which increases in the longitudinal direction from a narrow upper end to a wide lower end thereof. The filament will unwind from the bobbin member during ascent of the balloon causing the bobbin member to periodically oscillate in a manner such that the filament will unwind without fouling and at an appropriate rate.

Abstract: A drapery package comprising a core member and a drapery wrapped around it. The core member has a central portion and two end sections, the first of said two end sections containing a substantially uniformly spaced gap adjacent to said central portion, and the second of said two end sections containing a tapered spaced gap adjacent to said central portion. A longitudinally fan-folded drapery has a top end, a bottom end, and a middle section therebetween, the bottom end of said drapery being inserted into the substantially uniformly spaced gap of the first end section of the core member, the middle section of said drapery being wound in spiral fashion around the length of the core member, and the top end of the wound drapery being exposed. The wound drapery is packed in a box with its top end exposed so that drapery pins can be inserted along the top margin of the drapery even before it is removed from the box.

Abstract: An end cap for a paper board reel of unitary construction which is designed to be applied in an economical manner by production machinery and provides a smooth arcuate surface which avoids injury to cloth to be wound thereon.

Abstract: In order to form a package which includes a length of fabric which at one side edge region is substantially longer than at its other side edge region, the fabric is wound so as to form a wound body of fabric surrounding a given axis, and along the latter axis there is situated a core which has opposed free end regions which respectively have transversely with respect to said axis maximum dimensions one of which is substantially greater than the other. The core end region which is of the greater maximum dimension supports the fabric at its longer side edge region. The core preferably includes tubular and finned core portions, the latter having fins which project from the axis of the core, and the finned core portion extends partly into the tubular core portion.

Abstract: A one-piece winding reel for fabric made from corrugated cardboard in which the corrugations are aligned with the center line of the reel. In one embodiment self-locking end-flaps are provided to eliminate the need for fastening materials. In a second embodiment the end-flaps are permanently affixed to the structure in an alternative securing means.

Abstract: An end cap for a paperboard reel upon which cloth is to be wound which has its corners rounded instead of sharp so as not to injure cloth with which the reel might come in contact.

Abstract: A reel for yarn, ribbon, or the like is disclosed which consists of a pair of end pieces and a central web operatively connected therebetween about which the yarn or ribbon can be wound. The end pieces are of identical construction and each comprises a single blank of foldable material having a central section, at least two intermediate sections respectively joined to two sides of the central section along fold lines therebetween, and two end sections respectively associated with the intermediate sections along additional fold lines therebetween. The central section has at least one slot formed therein which receives the end flanges in the folded configuration of the end pieces. The intermediate sections are folded through approximately 180.degree. over the central section about the fold lines therebetween and the end sections of the blank are folded through approximately 90.degree.

Abstract: A new and improved cloth-board reel is disclosed which utilizes two corrugated sheets bonded together eliminating the need for an intermediary sheet which was previously considered necessary. The cloth-board reel of the present invention provides the required strength without the more expensive construction previously considered necessary. The corrugated sheets are covered with a wrapper sheet which forms a smooth surface for the cloth and adds to the strength of the cloth-board reel.

Abstract: A paperboard textile core has two self locking tabs at each end of the core to secure the core together.
