ORIGINAL
TO BECNPEE B PLCN InventionT Tte"BE COMHPELE BY, AESPLICANT SETIM ATeflown tateentoris): Fuldich ipECKER; Dr. inertin iA nduinfrthed bstUmeho o performing it known to me:- L O -2- The present invention relates to a re-shapeable or resilient sheet film for the production of shrinkable coverings, in particular for cable connections and junctions, consisting of at least one polymeric coating layer, a heat-stable netting layer and a heat-shrinkable re-shapeable or resilient layer.
A tubular woven fabric is already known for the protection or insulation of elongated objects, which is heat-shrinkable in the radial direction and is heatstable in the axial direction and which also has a heat-hardening layer in order to increase the rigidity of the product arising during the shrinkage procedure.
The capability of heat-shrinkage in the radial direction is achieved with the use 10 of heat-shrinkable synthetic plastics material threads and the heat-stability in the axial direction is achieved with the use of synthetic plastics material threads which are not heat-shrinkable (US-PS 36 69 157).
Furthermore, a heat-shrinkable product is also known which consists essentially of a heat-shrinkable woven fabric and a polymeric layer (cf. EP-OS 0 243 985).
15 The present invention is based upon the problem of creating a heat-re-shapeable sheet film of the type described initially which is distinguished by its high resistance to tearing in the fusible and solid state as well as high resistance to buckling in the solid state and is capable of being manufactured simply and economically.
Q-IF this wi. M tp of., having the re-shapeable layer made from a cross-linked c ed synthetic plastics material sheet film which, in the c ing direction or shrinkage direction, is divided up wit ormation of shrinkage strips of prescribed width by me s iiding cuts which either completely penetrate or do not otoly onrte-tho cynthcti.-platic materis Vshtic S i- 2a In accordance with the present invention, therefore, there is provided a heatreshapeable or resilient sheet film for the production of shrinkable coverings, consisting of at least one polymer cover layer, a heat-shrinkable re-shapeable or resilient layer and a heat-stable net layer between the polymer cover layer and the re-shapeable or resilient layer, wherein the re-shapeable layer is made from a crosslinked stretched plastics material sheet film which, in the stretching direction, is divided up with the formatica of shrinkage strips of prescribed width by means of dividing cuts which either completely penetrate or do inot completely penetrate the plastics material sheet film.
Very surprisingly, e* *e e
I
-3the result of these inventive measures is the achievement of a high resistance to tearing, even in the fusible state, more particularly in the s' rinkage direction because of the inventive configuration of the re-shapeable layer and orthogonally to the shrinkage direction because of the heat-stable cross-linked layer. In addition, a high degree of resistance to buckling in the solid state is guaranteed.
Additional features of the invention will be dealt with in what follows. Thus, the invention provides that the cross-linked stretched synthetic plastics material sheet film has at 200 'C a maximum shrinkage force of 200 p (p pond gramforce) per cm of sheet width, preferably from 1200 p per cm up to 1600 p per cm 10 of sheet width. The dividing cuts and/or superficial cuts may be at a distance apart of 1 mm up to 20 mm, preferably 1 mm up to 5 mm. Preferably the crosslinked stretched synthetic plastics material sheet film has cut-free borders of a pre-established width. They can be embedded between two netted layers or between one netted layer and two covering layers or else between two netted layers and two covering layers. Overall, the heat-re-shapeable synthetic plastics material sheet film advantageously possesses closure rails or cosure beadings disposed at right angles to the shrinkage direction. The dividing cuts and/or superficial cuts in accordance with the invention are disposed at right angles to the closure rails or at a pre-determined angle up to 45 preferably at an angle 20 from 80 to 85 In this connection, there is also the possibility that the dividing cuts and/or the superficial cuts are disposed at a prescribed angle in relation to each other, preferably from 5 up to 20 The dividing cuts and/or the superficial cuts may be interrupted over defined regions, where it is preferable for the cut regions and the uncut regions to alternate with each other.
In addition, the invention provides for the dividing cuts and/or the superficial cuts to cnd at a distance of 10 mm up to 30 mm away from the closure rails, or else for them to be continued right up to the closure rails and, if necessary, for only some of them end before reaching the closure rails or only some of them to -4be continued right up to the closure rails. In accordance with the present invention, the heat-stable netted layer may be formed from a netting, woven fabric, knitted fabric, mesh or the like fabricated from metal, synthetic plastics material or fibreglass, arranged so that they are resistant to displacement in the shrinkage direction. The possibility also exists that the netting, woven fabric, knitted fabric, mesh or the like may be fabricated from single or multiple-twisted threads. In addition, the netting, woven fabric, knitted fabric, mesh or the like may include adhesion-promoting threads or else may be saturated with a liquid adhesive agent in order to achieve an especially secure attachment to the reshapeable layer of the synthetic plastics material sheet film and the associated S. covering layer. This an also be achieved if the netted layer is connected to the *cross-linked stretched synthetic plastics material sheet film in a heat-stable 4 *o manner by means of adhesive or by sewing and/or chain-linking and, if necessary, the warp and the weft threads of the netted layer are firmly connected together. The warp and weft threads of the netted layer which cross over each other may be disposed parallel, or at right angles, to the closure rails, or else be disposed at a pre-determined angle of up to 45 to said closure rails.
S. o It is more expedient for the longitudinal (warp) threads to be disposed at a distance apart of 1 mm up to 40 mm, preferably 2 mm up to 10 mm, and for the weft threads to be disposed at a distance apart of 0.5 mm up to 20 mm, preferably 1 mm up to 3 mm. Last, the upper and/or the lower covering layer preferably the lower layer can be a barrier layer made from aluminium to block the access of steam.
In what follows an example of embodiment of the invention will be described in greater detail with reference to the accompanying drawing: the only Figure is a perspective view of a heat-re-shapeable or re-lient sheet film 1 in accordance with the invention, partly in section or with partly exposed layers. The sheet film serves for the production of cable sheaths, housings, sleeves or the like for objects, in particular shrinkable coverings for cable connections and junctions, consisting of at least one polymeric coating layer 2, a heat-stable netting layer 3 and a heat-shrinkable re-shapeable layer 4. In accordance with the example of embodiment, there is an upper 2 and a lower 5 polymeric covering layer, as well as an upper 3 and a lower 6 heat-stable netted layer, provided for the embedded heat-shrinkable re-shapeabl layer 4. The re-shapeable layer consists of crosslinked stretched synthetic plastics material sheet film 4 which, in the stretching direction or shrinkage direction indicated by the double-headed arrow is divided up by dividing cuts 7 which penetrate through the synthetic plastics material sheet film 4, thus forming shrinkage strips 8 of pre-determined width.
The synthetic plastics material sheet film has a maximum shrinkage force at 200 C of 200 p per cm of sheet width, preferably from 1200 p per cm up to 1600 p per cm of sheet width. The dividing cuts and/or superficial cuts may be at a O distance apart of 1 mm up to 20 mm, preferably 1 mm up to 5 mm, so that genuine shrinkage strips 8 are established between these dividing cuts 7.
a.
In addition, the synthetic plastics material sheet film 4 has cut-free borders of a S pre-established width and has closure rails 9 or closure beadings disposed at right angles to the shrinkage direction. The dividing cuts 7 in accordance with the example of embodiment of the invention are disposed at right angles to the 20 closure rails 9 but can also be at a pre-determined angle up to 45 preferably at an angle from 80 to 85 and furthermore, they may be disposed at a prescribed angle, preferably 5 up to 20 towards or away from each other.
This latter arrangement is not depicted. In addition, ir. ccoidance with the example of embodiment of the present inventic;a, the dividing cuts may be continued through right up to the closure rails 9, but they may also end at a prescribed distance away from the closure rails, or only some of them may before reaching the closure rails and the remainder of them may be continued through right up to the closure rails.
-6- In the case of the heat-stable netted layers 3, 6 in the example of embodiment depicted, it is a matter of a woven fabric or mesh, which is arranged to be resistant to displacement in the shrin:age direction. The woven fabric or mesh 3, 6 may be fabricated from metal, synthetic plastics material or fibreglass. The possibility also exists that the fabric or mesh 3, 6 may be fabricated from single or multiple-twisted threads. In addition to this, the fabric or mesh 3, 6 is saturated with a liquid adhesion-promoting medium. The mutually crossed-over warp threads 10 and weft threads 11 of the woven fabric or mesh 3, 6 are disposed either parallel, or at right angles, to the closure rails 9, but an arrangement at a prescribed angle up to 45 to the closure rails is also possible.
According to the example of embodiment, the distances between the warp threads 10 and weft threads 11 in each case may be several millimetres.
Preferably, the lower covering layer 5 may be a barrier layer made from 4* aluminium or from aluminium foil, but this is not depicted as such.
15 Within the scope of the invention, the distance of the dividing cuts 7 along the length of the sheet film 1, in which it may be a matter of a sleeve, may be varied. The aluminium foil may likewise be cut in the shrinkage direction of the sheet film. This eliminates its effectiveness as a barrier against steam or vapours but, none the less, it retains its effect as a heat reflector. The covering layer 2 20 exhibits a thixotropic behaviour so that the covering layer(s) are readily deformable in the shrinkage region, without flowing off as a liquid.
