Abstract
Abstract A cable sleeve for covering a cable splice. An enveloping hose of heat shrinkable material is on its inside provided with a hot melt adhesive coating. A device designed cross-shaped in cross-section for support of the cable ends is inserted between the cables. The device is of hot melt adhesive whose fusion point is below that of the material of the hot melt adhesive coating.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A cable sleeve for covering a cable splice formed by cables having ends, comprising an enveloping hose of heat shrinkable material, a hot melt adhesive coating covering at least some portions of the inside surface of the hose, and at least one device cross-shaped in cross-section for insertion between and support of cable ends to be entered into the cable sleeve wherein the device is a molded piece of hot melt adhesive and wherein the fusion point of the hot melt adhesive of the device is below the fusion point of the hot melt adhesive of the coating.
Claim 2
Dependent Claim
98 words
A cable sleeve for covering a cable splice formed by cables having ends, comprising an enveloping hose of heat shrinkable material, a hot melt adhesive coating covering at least some portions of the inside surface of the hose, and at least one device cross-shaped in cross-section for insertion between and support of cable ends to be entered into the cable sleeve wherein the device is a molded piece of hot melt adhesive and wherein the fusion point of the hot melt adhesive of the device is below the fusion point of the hot melt adhesive of the coating.
Claim 3
Dependent Claim
34 words
A cable sleeve according to claim 1, comprising at least one additional device cross-shaped in cross-section to be inserted between cable ends and spaced in longitudinal direction of the cables apart from the device.
Claim 4
Dependent Claim
22 words
A cable sleeve according to claim 2, wherein the distance between the two devices is smaller than the length of each device.
Claim 5
Dependent Claim
23 words
A cable sleeve according to claim 2, wherein the distance between the two devices is smaller than half the length of each device.
Claim 6
Dependent Claim
63 words
A cable sleeve according to claim 1, comprising a ribbon of hot melt adhesive for surrounding cables and at least two devices for insertion between the cables and located underneath the enveloping hose, wherein the fusion point of the hot melt adhesive of the ribbon is lower than the fusion points of the hot melt adhesives of the devices and of the coating.
Claim 7
Dependent Claim
22 words
A cable sleeve according to claim 5, wherein the central area of the enveloping hose is free of hot melt adhesive coating.
Claim 8
Dependent Claim
33 words
A cable sleeve according to claims 5 or 6, wherein the outwardly facing edge portions of the cross-shaped devices are of increased thickness, the outer edges forming a contact surface for the ribbon.
Claim 9
Dependent Claim
145 words
A process for covering a cable splice formed by cables having ends, comprising the steps of inserting a cross-shaped device of hot melt adhesive between cable ends to be spliced, placing an enveloping hose having an inside coating of hot melt adhesive over the cable ends, and fixing the device in position by applying heat to the hose, wherein the fusion point of the hot melt adhesive of the device is lower than the fusion point of the material of the inside coating of the hose, applying further heat until the fusion point of the hot melt adhesive of the coating is exceeded so that the hot melt adhesive of the coating fills the cavities existing between the cables and the hot melt adhesive of the coating is prevented by the device from exiting out from between the cables at the end of the hose.
Claim 10
Dependent Claim
145 words
A process for covering a cable splice formed by cables having ends, comprising the steps of inserting a cross-shaped device of hot melt adhesive between cable ends to be spliced, placing an enveloping hose having an inside coating of hot melt adhesive over the cable ends, and fixing the device in position by applying heat to the hose, wherein the fusion point of the hot melt adhesive of the device is lower than the fusion point of the material of the inside coating of the hose, applying further heat until the fusion point of the hot melt adhesive of the coating is exceeded so that the hot melt adhesive of the coating fills the cavities existing between the cables and the hot melt adhesive of the coating is prevented by the device from exiting out from between the cables at the end of the hose.
Claim 11
Dependent Claim
128 words
A process according to claim 8, comprising winding a ribbon of hot melt adhesive material onto the cables prior to mounting the hose, slightly heating the ribbon for a short period and pressing the ribbon onto portions of the cable surfaces and the outer edges of the devices so as to adhere thereto, sliding the enveloping hose over the ribbon, wherein the enveloping hose has inside coatings of hot melt adhesive material at the ends thereof so as to form a middle portion without hot melt adhesive coating, and heating the middle portion of the hose so as to shrink the hose onto the ribbon, and applying further heat in order to melt the hot melt adhesives of the ribbon and of the coating of the enveloping hose.
