US 5,400,567 A · Method of manufacturing a coil of a continuous flexible object and enveloping the coil to form a parcel

Abstract

A method of manufacturing a coil (1) of a continuous flexible object (2), such as cable and line, and enveloping the coil to form a parcel (27) for delivery to a user, said object (2) being coiled onto an axially open, cylindrical sleeve (28) to produce said coil. According to the invention the sleeve (28) is provided with two protective rings (29, 30) and is brought to be fixed by a first tool (9) so that the sleeve (28) is firmly clamped between two parallel side supports (10, 11) and centered by centering elements (24) of the side supports, whereby a first rotatable unit (36) is formed. The cable or line (2) is attached to said first unit (36) and the unit (36) is brought to rotate in a coiling machine (3) so that the cable or line is formed to said coil (1). When the cable or line has been cut, a protective casing (40) is brought to surround the coil ( 1) between the protective rings (29, 30), and a plurality of bands (41) are brought to surround the sleeve (28) from the inside thereof, the protective rings (29, 30), the protective casing (40) and the coil (1) enclosed within these parts, without engagement with the side supports (10, 11), after which the bands (41) are tightened and their ends joined in a strong joint to form said parcel (27). A system is also described for handling the cable or line which is prepared and enveloped in the manner described, as well as tools of the structure described above and cable or line parcels manufactured according to said method.

Dependent claims

A method of handling a coil of a continuous flexible object, using a hollow sleeve, a pair of fiat protective rings dimensioned to cooperate with opposite axial ends of the sleeve, a pair of side supports, a shaft releasably connectable to the side supports, and a coiling machine including bearing means, said method comprising the steps of substantially sequentially:

(a) providing the sleeve between the protective rings and the pair of side supports at opposite axial ends thereof with said protective rings engaging said side supports and the axial ends of the sleeve, with the shaft passing through and unconnected to the hollow sleeve except at the opposite axial ends thereof, and releasably connecting the shaft and both side supports, to produce a rotatable unit;
(b) journalling the rotatable unit in the coiling machine by moving the bearing means into operative association with the rotatable unit;
(c) attaching the continuous flexible object to the rotatable unit;
(d) with the coiling machine, rotating the rotatable unit so that the continuous flexible object is wound to form a coil of the continuous flexible object wrapped around the sleeve;
(e) cutting the continuous flexible object after a coil of desired dimensions has been formed, defining a free end of the continuous flexible object;
(f) placing a protective casing around the coil concentric with the sleeve, distinct from the side supports;
and
(g) binding the protective casing to the sleeve and protective rings to hold the coil tightly on the sleeve without relative movement between turns of the coil, to produce a package.
