DESCRIPTION:
BRIEF SUMMARY
The invention relates to a suspension sleeve for snood swivels, comprising an annular rectangular metal plate for rotating around the longitudinal axis of a fishing line, said annular plate having two facing end areas. The invention further relates to a method of making a such suspension sleeve.
Suspension sleeves of this type are known from e.g. WO92/01372 and are used in order to prevent the snoods from becoming tangled on the taut fishing line and to reduce the length of the freely suspended section of the snoods, thus making it easy for the fish which have been caught to disengage themselves.
In order to restrict the movement of the suspension sleeve along the line a stop ring is shrunk on to the line on each side of the suspension sleeve. Alternatively, in other prior art, a sliding sleeve with enlarged end sections has been moulded on to the line to form a sliding bearing for a plate curved around the sliding sleeve's central section, and which thus constitutes a suspension sleeve able to rotate easily and without the risk of its causing wear on the line, but the enlarged end sections of the sliding sleeve restricting the suspension sleeves' movement along the line.
The suspension sleeves, hereinafter called the sleeves, are made of a rectangular metal plate which is bent into an annular shape. In order to secure the swivel, a central section of the annular plate can have a radially outwardly projecting, approximately spherical segment shaped section, wherein there is provided a central slot which extends parallel to the ring's longitudinal axis. However the ductility of the material of which the plate is made is usually low. Consequently the maximum height of the spherical segment section is limited.
In this design of sleeves the swivel can be made of a piece of metal wire, whose thickness is slightly less than the width of the slot. One end section of the metal wire is composed of a straight neck section which ends in an enlarged section or a head and the other end section of the metal wire is bent in a plane in into the shape of a hook, the head's diameter being smaller than the spherical segment section's height.
Before the plate is curved into an annular shape around the line or the sliding sleeve, the swivel is threaded through the slot until only the head is located inside the spherical segment and the head abuts against it, whereafter the plate is bent around the line or the sliding sleeve. The head of the swivel is thus enclosed with clearance between the sleeve and the line or sliding sleeve, and can be moved in the raised section, its neck section protruding out through the slot.
When the snood is under a heavy lead, the sleeve may work loose from the line, the bending moment which is exerted against the sleeve causing one or both end sections of the plate of which it is made to become bent radially outwards, thus causing the opening or split between the end sections to become larger than the diameter of the line or the sliding sleeve.
When the line is hauled in it pulled on board successively by means of a driven wheel with a circumferential, radially outwardly open groove with a V-shaped cross section, in which groove a section of the line is first placed and clamped. When the wheel rotates the line becomes more securely clamped the greater the tension in the line.
The width of the track at the opening is smaller than the external diameter of the sleeves. When the line is hauled in, those sleeves which are attached to the section of the line which is located at the driving wheel will thus be made to abut against the edges of the groove's opening, as the adjacent line sections attempt to pull the sleeves radially inwards on the wheel.
During the preparations for renewed fitting the line and the snoods receive separate treatment. For this reason the sleeves are rotated, thus causing the swivels to turn radially outwards in relation to the wheel. At the same time the sleeves and the swivels are pushed towards the periphery of the wheel and the swivels attempt to move into a position in whic
