Abstract
Device for winding a cable on a drum in such manner as to form turns each comprising a circular portion extending over the major part of its circumference and connected to an adjacent turn by a short oblique portion, wherein the cable in the course of winding is guided by a cable guide member, means being provided to displace this member step-by-step along the drum in rotation, in such manner as to keep it stationary during the major part of each revolution of the drum and to displace it by one step over a distance equal to the diameter of the cable while the drum is completing its revolution.
Claims8
A device for winding a cable onto a rotating drum, comprising a cable guide member, and control means comprising a cylinder having a guide track formed in the peripheral surface thereof, said guide track having portions of circular arc form connected by short oblique portions, means mounting the cylinder rotatably, means for rotating the cylinder at a speed proportional to the speed of rotation of the drum, a power operated reader having a reading head carrying a feeler engaging the guide track and compelled to follow the same, means for driving the cable guide member, and means for actuation of the driving means from the reading head.
A device for winding a cable onto a rotating drum between two side members of the drum, comprising a cable guide member and step-by-step displacement control means to keep the cable guide member stationary during a major part of a revolution of a drum in order that the cable may wind onto the drum forming a circular turn portion extending over a major part of the circumference of the drum, and to displace the cable guide member along the drum by a step having a length equal to the cable diameter during the remaining part of the revolution of the drum in order that the cable may form a short oblique turn portion on the drum, in which the control means comprise means to keep the cable guide member stationary during a supplementary revolution after the winding of the circular portion of the last turn of each layer, and to displace the cable guide member by one step in the direction away from the side member adjacent to the said last turn.
A device for winding a cable onto a rotating drum between two side members of the drum, the distance between said side members being equal to an odd number of half cable diameters, comprising a cable guide member, step-by-step displacement control means to keep the cable guide member stationary during a major part of a revolution of a drum in order that the cable may wind onto the drum forming a circular turn portion extending over a major part of the circumference of the drum, and to displace the cable guide member along the drum by a step having a length equal to the cable diameter during the remaining part of the revolution of the drum in order that the cable may form a short oblique turn portion on the drum, an abutment member to keep the circular portion of an end turn of the first layer at a distance from the adjacent side member equal to a half diameter of the cable, and means for displacing the cable guide member by a half step after the winding of the circular portion of the last turn of each layer.
