Abstract:
Apparatus for taking-up a line comprising:a frame on which a take-up drum for the line is mounted so as to be rotatable about an axis,a rotary drive for driving said take-up drum, said rotary drive being arranged within said take-up drum, anda rotary coupling between a line terminal fixed to the frame and a line terminal fixed to the take-up drum, wherein:the rotary coupling comprises a first auxiliary drum which co-rotates with the take-up drum and a second auxiliary drum which is fixed relative to the frame,said auxiliary drums are arranged coaxially with an axis of rotation,the rotary coupling comprises a rotating element which is rotatable about the rotation axis at a lower speed than the first auxiliary drum,the rotary coupling comprises a connection line which is fixed on one side relative to the take-up drum and is fixed on the other side relative to the frame,said connection line extends without twisting and is windable onto or unwindable from the first auxiliary drum,said connection line passes from the first auxiliary drum to the rotating element in a first strand and passes from the rotating element to the second auxiliary drum in a second strand and is unwindable from or windable onto said second auxiliary drum,the rotating element provides that the first strand and second strand extend substantially without sagging, andin its rotational movement, the rotating element takes up the line length unwound from the one auxiliary drum and delivers the line length wound onto the other auxiliary drum.
