Cable-twisting two yarns

An apparatus for twisting together a first and a second yarn, said apparatus comprising:

• a frame;
• a generally V-shaped first holder having a pair of arms each having an outer end provided in turn with an elongated support pin adapted to carry a respective supply of said first yarn, whereby the tail end of said first yarn of one of said supplies can be connected to the starting end of the other of said supplies, said pins being relatively inclined;
• a second holder adapted to support a supply of said second yarn;
• a rotatable takeup spool on said frame underneath said first holder;
• support means pivotally supporting said first holder on said frame for displacement substantially in an upright plane between an operating position relatively far above said takeup spool and a loading position below and horizontally offset from said operating position, said pins and arms being generally coplanar and in said plane;
• respective first and second guide means between said first and second holders and said takeup spool for feeding said first and second yarns from said first and second supplies to said takeup spool;
• a yarn guide on said first holder and lying generally at the intersection of the longitudinal axes of said pins and between said supplies of said first yarn and said first guide means, said yarn guide being displaceable substantially in said plane on displacement of said first holder between said operating and loading positions;
• means for pivoting each of said pins between an inner position on said plane and an outer position offset from said plane;
• and
• takeup drive means for rotating said takeup spool and thereby winding said first and second yarns up on said spool.

An apparatus for twisting together a first and a second yarn, said apparatus comprising:

• a frame;
• respective first and second holders respectively adapted to support supplies of the first and second yarns;
• a rotatable takeup spool on said frame underneath said first holder;
• support means pivotally supporting said first holder on said frame for displacement substantially in an upright plane between an operating position relatively far above said takeup spool and a loading position below and horizontally offset from said operating position and generally level with said takeup spool, said support means being a parallelogrammatic linkage including a pair of generally parallel long links having inner ends pivoted at respective inner pivot axes on said frame and an outer transverse link carrying said first holder, said long links having outer ends pivoted at respective outer pivot axes on said outer transverse link, said pivot axes all being substantially parallel and perpendicular to said plane;
• respective first and second guide means between said first and second holders and said takeup spool for feeding said first and second yarns from said first and second supplies to said takeup spool;
• and
• takeup means for rotating said takeup spool and thereby winding said first and second yarns up on said spool.
