Abstract
In a method for splicing filaments, respective end portions of two filaments are held in overlapping condition in a holding device comprising two axially spaced rubber holders, each holder having a radial slot for receiving and retaining the overlapped end portions. One of the holders is rotated relative to the other to twist together the overlapping end portions. The holders are then fixed against relative rotation, and the twisted together end portions are fused together to form a splice of substantially circular cross-section. The method and device are useful for splicing plastic coated glass yarn used to reinforce telecommunications cables.
Claims15
A method for splicing filamentary material comprising overlapping respective end portions of two pieces of filamentary material by arranging the pieces to extend in opposite directions with respective end portions of the pieces alongside one another, holding the pieces of filamentary material at two axially spaced holding positions and rotating the filamentary material at one holding position with respect to the filamentary material at the other holding position to twist the overlapped end portions together, and treating the twisted end portions to cause the twisted end portions to adhere to one another.
A device for holding filamentary material during splicing, comprising a pair of holding means locatable in axially spaced positions for holding respective end portions of two pieces of filamentary material in overlapping condition, said holding means being rotatable one with respect to the other to twist together the end portions, and rotation resisting means for resisting rotation of the holding means one with respect to the other.
A device for holding filamentary material during splicing, comprising a pair of resilient holders each having a slot opening onto a peripheral surface of the holder and extending axially through the holder for receiving and holding respective end portions of two pieces of filamentary material in an overlapping condition, the holders being rotatable one with respect to the other to twist together the end portions, and a sleeve having open ends for receiving and retaining the holders, and a lateral opening extending between the open ends of the sleeve for permitting lateral movement of the filamentary material into and out of the sleeve, the holders being rotatable one with respect to the other when separate from the sleeve and the sleeve frictionally resisting relative rotation of the holders when the holders are received therein.
A device for holding filamentary material during splicing, comprising a pair of of resilient holders each having a slot opening onto a peripheral surface of the holder and extending axially through the holder for receiving and holding respective end portions of two pieces of filamentary material in an overlapping condition, the holders being rotatable one with respect to the other to twist together the end portions, and a pair of spaced supports for supporting the holders in axially spaced positions, one of the holders being fixed against rotation on its support, and the other of the holders being manually rotatable against a frictional braking force on its support.
