Abstract

Abstract © Apparatus for laying of optical waveguides (16) into sinuous grooves (52) of a support filament (10) in which a laying device surrounding a feed path for the filament has a plurality of elongate guide elements (56) for the waveguides, the elements extending downstream from a carrier (42) and being inclined to the feed path to terminate in free inner ends. The guide elements are rigid and are allowed by the carrier to have lateral swinging movement to enable their free ends to follow the path of a groove in the support filament as it moves along its feed path. A groove locating projection (50) is provided to maintain positional relationship between the carrier and support filament as the filament passes the carrier.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 161 words
An apparatus for laying optical waveguides into sinuous grooves of a support filament comprising a laying device disposed around the feed path for the support filament, the device comprising a plurality of elongate guide elements and a carrier, the guide elements extending downstream from the carrier and inwardly to free inner ends of the guide elements, characterized in that the guide elements (56) are rigid and are held by the carrier (42) to allow for lateral swinging movement of each guide element to provide a change in angle of orientation of the guide elements relative to the feed path so as to enable the inner end of the element to follow the path of a groove in the support filament as it moves downstream from the carrier; and at least one groove locating projection (50) for engagement with a groove in the support filament to retain positional relationship between the carrier and support filament as the filament passes through the carrier.
Claim 2
Independent Claim 161 words
An apparatus for laying optical waveguides into sinuous grooves of a support filament comprising a laying device disposed around the feed path for the support filament, the device comprising a plurality of elongate guide elements and a carrier, the guide elements extending downstream from the carrier and inwardly to free inner ends of the guide elements, characterized in that the guide elements (56) are rigid and are held by the carrier (42) to allow for lateral swinging movement of each guide element to provide a change in angle of orientation of the guide elements relative to the feed path so as to enable the inner end of the element to follow the path of a groove in the support filament as it moves downstream from the carrier; and at least one groove locating projection (50) for engagement with a groove in the support filament to retain positional relationship between the carrier and support filament as the filament passes through the carrier.
Claim 3
Dependent Claim 41 words
Apparatus according to claim 1 characterized in that each of the guide elements is moveable longitudinally of its axis relative to the carrier and stop means (74, 96) is provided to limit the amount of longitudinal movement of each guide element.
Claim 4
Dependent Claim 33 words
Apparatus according to claim 1 characterized in that the carrier is angularly displaceable around the feed path to enable the guide elements to follow the path of grooves formed in a support filament.
Claim 5
Dependent Claim 25 words
Apparatus according to claim 1 characterized in that the guide elements are rigid tubes (56) loosely mounted within the carrier to provide the swinging movement.
Claim 6
Dependent Claim 52 words
Apparatus according to claim 2, characterized in that the guide elements are rigid tubes (56) loosely mounted within the carrier to provide the swinging movement and the stop means is a plate member (74) disposed upstream of the tubes and for engagement by the tubes at the limit of their longitudinal movement.
Claim 7
Dependent Claim 50 words
Apparatus according to claim 2 characterized in that the guide elements are rigid tubes (56) loosely mounted within the carrier to provide the swinging movement and the stop means is an annular member (96) surrounding and secured to each tube and for engagement with a downstream part of the carrier.
