A hub, on which compressing of the inner central bore is to be minimized during the winding up of an information medium in tape form under high winding pressure. According to one embodiment, this is achieved by an outer hub ring having a strong profile being provided alongside the outer winding area and by there also being elastically deformable intermediate elements between outer hub ring and inner hub ring. Such elements provide for a compression ratio of the compressed diameters of a the inner to the outer ring of less than 1:4. In the case of a further embodiment, variously shaped openings or notches, which are distributed evenly over the entire circumference, are provided on both sides of the hub between its outer circumference and inner circumference. In a still further embodiment the elastically deformable intermediate elements consist of webs running in radial and circumferential directions and residual portions between openings provided between the periphery of the outer ring and said webs.

Winding hub for information carriers in tape form

A support for at least a single annular body or a plurality of stacked annular bodies, comprising a hollow cylinder and retaining bodies with flanges and annular attachments and also provided with hook devices for at least one tensioning element, whereby the parts of the support itself and the annular body or the annular bodies are held together or stored. The support can be used for any type of rings, annular plates etc. and also of wound-up bodies in band form.

Multipack for magnetic tapes wound onto hubs

The invention relates to parallelepipedal packaging containers for recording media in tape form which are wound up onto hubs provided with internal bores and are stacked one on top of the other, comprising a bottom part, a top part and side parts, which are joined to one another by means of molded-on film hinges, and it being possible for a hub support to be pushed through the internal bores of the hubs.

Multipack for recording media in tape form wound onto hubs

A ring part and individual winding hub combination comprises a single-flange ring part with or without spring elements on the receiving circumference for the internal bore of the associated winding hub, which has or does not have spring elements between the internal bore and outer circumference. Receiving circumferential rim and internal bore may expediently be designed with intermeshing toothings.

Winding hub device for tapes

A description is given of a cuboidal multipack for vertically stacked magnetic recording media, comprising a rectangular pallet, a baseplate and top plate and wound roll sets stacked between two intermediate plates in each case, the tape rolls being wound up on flangeless winding hubs provided with internal bores, through which a hub sleeve is inserted, the pack being protected by edges and side parts and a stretch film being drawn around the entire unit. To be able to stack a large number of wound rolls one on top of the other without the risk of damaging the edges of the tape rolls, each intermediate plate, which is provided on its upper side and under side with a ring groove, is supported by means of the end face of the hollow-cylindrical hub sleeve by the next-lower intermediate plate, so that merely the wound pack accommodated in one set is placed with its weight able to bear on an intermediate plate. The intermediate plates may include on their outer edges projections and grooves assigned to them, so that they are able to be transported stacked one on top of the other on the same pallet in return shipment. It is assured by the material selection of the multipack that the entire pack part can be brought into a clean room without the risk of dust and can be taken off with little effort.

Reusable multipack for stacked wound rolls

A hollow-cylindrical supporting core for pancakes which is produced from recyclable plastic by injection molding is described, the arms, which may be angled off, which extend from the gating point and run to the inside diameter of the supporting core remaining in place after demolding of the injection mold and being suitable as holding grips for the supporting core.

Supporting core for wound-up recording media

Parallelepipedal packaging containers, suitable for return transport, for wound-up magnetic recording media, produced from a one-part or multi-part blank having a bottom and top as well as side parts, which are joined to one another by means of foldable joining tabs and containing a hub support extending from the top to the bottom. The bottom and the top each have a circular central clearance through which a one-part or multi-part hollow-cylindrical hub support is inserted, onto which the wound media are fitted in a stackable manner. For assembly of the package from the folded-up state, the hub support has a locking snap-in device on at least one end face.

A one-part container produced by injection molding for reeled magnetic tape, for example 1' video tapes, is described, the container comprising a bottom tray and a top tray, which are connected to each other by means of a folding line provided with bends, there being provided on a bevelled-off edge of the bottom tray and of the top tray holding grip parts, which are joined together to form a holding grip when the container is closed up. The container includes inside it a hub arresting means, in the bottom part and in the top part an annular projection for receiving or supporting the reel, the reel being mounted rotatably in the interior. Furthermore, the container includes lugs on the side walls for closing by snapping in of the container. The side walls are shaped such that, by virtue of elevations which engage in correspondingly shaped grooves in the other part of the container, the content is stored in a manner protected against dust and moisture.

Reel container for magnetic tapes

The multipack for pancakes of relatively large diameter comprises two end plates (1, 2) and an intermediate plate (4), anchored on which is a tube (3) on which the pancakes are arranged in series with cushioning disks placed in between. The end plates include fixing means on their narrow sides for stacking a plurality of the multipacks described on top of and next to one another on one and the same pallet. A film of plastic is drawn over each multipack and each multipack is held together by securely lashed straps, which are drawn over the end plates.

Multipack for wound rolls

A right-parallelepipedal multipack for vertically stacked wound rolls, comprising a rectangular pallet (1), a rectangular base plate (3), located on said pallet and provided with a multiplicity of clearances (2), an identically constructed intermediate plate (5) and a likewise identical top plate (6), a multiplicity of wound rolls (4) respectively stacked in-between and means (7, 8, 9) for fixing the pack and the wound rolls, wherein the wound rolls are recording media (10) in tape form which are wound-up on flangeless hubs (11) which are provided with inner bores and through which there is fitted a hub sleeve (8) which is mounted non-displaceably in the clearances (2) of the base plate (3), intermediate plate (5) and top plate (6), and a cover (9), provided with a ring, being adapted to fit onto the upper end of the hub sleeve (8) above the top plate, the lateral four corners of the pack being secured by vertically attached corner parts (7) and a stretch film (12 ) being drawn around the side parts of the pack.

Abstract of the Disclosure: A flangeless stackable hub, on which compressing of the inner central bore is to be prevented during the winding up of an information medium in tape form under high winding pressure. According to one embodiment, this is achieved by an outer hub ring having a double-T profile being provided alongside the outer winding area and by there also being elastically deformable annular intermediate elements between outer hub ring and inner hub ring. In the case of another embodiment, variously shaped openings or notches, which are distributed evenly over the entire circumference, are provided on both sides of the hub between outer circumference and inner circumference. In addition, the hub contains alongside its inner circumference on both sides axial deformations, in order to avoid a shifting or twisting when hubs are stacked one on top of the other (FIG. 2, FIG. 4).
