The line assembly forms a loop with a lower length and an upper length. A ribbon material either in a drum or coil is provided that fits inside the loop wherein the coil of ribbon material is between the upper and lower lengths of the line reinforced assembly and extends and retracts in the same direction as the movement of the loop and lengths of the assembly. The ribbon material is different from the material of the line assembly and is preferably stainless steel. A double ended system with two line assemblies operating in a single trough is also provided. ## Claims ### Claim 1 A line guiding assembly having a stationary piece of equipment and a moving piece of equipment comprising: (a) a plurality of cables held together within an encapsulant and further held within reinforcement channels to form a reinforced line assembly; (b) a trough holding said reinforced line assembly wherein said reinforced line assembly is positioned within the trough and looped back onto itself thereby forming a lower length, an upper length and a loop of the reinforced line assembly, wherein one of said lengths has an end which is affixed to the stationary piece of equipment and the other said length has an end which is affixed to the moving piece of equipment which is capable of moving in a longitudinal direction; (c) a ribbon material located between and intermediate said upper and lower lengths of the reinforced assembly, said ribbon material capable of extending and retracting as said upper and lower lengths move so that the ribbon material prevents said upper and lower lengths from touching, and wherein the material comprising the ribbon material is different from the encapsulant and reinforcement channel of the line assembly; and (d) a drum located within said loop of the line assembly wherein said ribbon material is affixed to the drum and wherein the drum rotates so as to roll up and unroll the ribbon material as the upper and lower lengths move within the channel. ### Claim 2 (depends on 1) A line guiding assembly of claim 1 wherein said encapsulant of the reinforced line assembly is polyurethane. ### Claim 3 (depends on 1) A line guiding assembly of claim 1 wherein said reinforcement channels of the reinforced line assembly is a polymeric material selected from the group including polyamides, and composites of polyamides and fluoropolymers. ### Claim 4 (depends on 3) A line guiding assembly of claim 3 wherein said fluoropolymers include polyethylene, fluorinated ethylene propylene, and perfluoroalkoxy resin. ### Claim 5 (depends on 1) A line guiding assembly of claim 1 wherein said trough is made of metal and is lined with an ultra-high molecular weight polyethylene. ### Claim 6 (depends on 1) A line guiding assembly of claim 1 wherein said ribbon material is made of a thin ribbon of stainless steel. ### Claim 7 (depends on 1) A line guiding assembly of claim 1 wherein said ribbon material is selected from the group consisting of beryllium copper, polyimides, cold rolled steel, and chrome-plated steel. ### Claim 8 (depends on 1) A line guiding assembly of claim 1 wherein said cables are selected from the group consisting of electrical cables, tubes, and fiber optics. ### Claim 9 A double ended line guiding system comprising two line guiding assemblies facing each other, wherein each of said line guiding assemblies having a stationary piece of equipment and a moving piece of equipment comprises: (a) a plurality of cables held together within an encapsulant and further held within reinforcement channels to form a reinforced line assembly; (b) a trough holding said reinforced line assembly wherein said reinforced line assembly is positioned within the trough and looped back onto itself thereby forming a lower length, an upper length and a loop of the reinforced line assembly, wherein one of said lengths has an end which is affixed to the stationary piece of equipment and the other said length has an end which is affixed to the moving piece of equipment which is capable of moving in a longitudinal direction; (c) a ribbon material located between and intermediate said upper and lower lengths of the reinforced assembly, said ribbon material capable of extending and retracting as said upper and lower lengths move so that the ribbon material prevents said upper and lower lengths from touching, and wherein the material comprising the ribbon material is different from the encapsulant and reinforcement channel of the line assembly; and (d) a drum located within said loop of the line assembly wherein said ribbon material is affixed to the drum and wherein the drum rotates so as to roll up and unroll the ribbon material as the upper and lower lengths move within the channel. ### Claim 10 A dual line guiding assembly comprising two line guiding assemblies held together within a single trough, wherein each of said line guiding assemblies having a stationary piece of equipment and a moving piece of equipment comprises: (a) a plurality of cables held together within an encapsulant and further held within reinforcement channels to form a reinforced line assembly; (b) a trough holding said reinforced line assembly wherein said reinforced line assembly is positioned within the trough and looped back onto itself thereby forming a lower length, an upper length and a loop of the reinforced line assembly, wherein one of said lengths has an end which is affixed to the stationary piece of equipment and the other said length has an end which is affixed to the moving piece of equipment which is capable of moving in a longitudinal direction; (c) a ribbon material located between and intermediate said upper and lower lengths of the reinforced assembly, said ribbon material capable of extending and retracting as said upper and lower lengths move so that the ribbon material prevents said upper and lower lengths from touching, and wherein the material comprising the ribbon material is different from the encapsulant and reinforcement channel of the line assembly; and (d) a drum located within said loop of the line assembly wherein said ribbon material is affixed to the drum and wherein the drum rotates so as to roll up and unroll the ribbon material as the upper and lower lengths move within the channel. ### Claim 11 (depends on 10) A double line guiding assembly of claim 10 further comprising a strain relief clamp holding said upper lengths of said two line guiding assemblies.
