Method of and apparatus for forming a leno selvage on woven goods

In combination with a loom having harnesses carrying an array of warp yarns defining a warp direction and displaceable in a shed direction transverse to said warp direction to form a main shed adapted to receive a weft passed through said shed in a weft direction transverse to said warp and shed directions, a leno selvage device comprising:

• a doup heddle at an edge of said array carrying a doup warp yarn and pivotal for displacement thereof in said weft direction;
• a rigid ground heddle at said edge carrying a ground warp yarn and having an end turned toward said doup heddle and constituting a support defining a rocking axis nondisplaceable in said weft direction;
• means for displacing one of said heddles synchronously with said harnesses toward and past the other heddle to form an edge shed in line with said main shed;
• means for urging said doup heddle into a position aligned in said shed direction with said ground heddle;
• a rocker pivotal on said end of said ground heddle at said support about said axis between a pair of end positions, said doup heddle being operatively engageable with said rocker and deflectable thereby in said weft direction in one of said end positions to one side of said ground heddle and in the other end position to the other side of said ground heddle;
• and
• means for displacing said rocker from said one end position into said other end position after deflection of said doup heddle into said one side and from said other end position into said one end position after deflection of said doup heddle to said other side of said ground heddle.

• a doup heddle at an edge of said array having an eye through which a doup yarn passes;
• a rigid ground heddle at said edge having an end turned toward said doup heddle and provided with a tube through which a ground warp yarn passes and defining a rocking axis nondisplaceable in said weft direction;
• means for displacing one of said heddles synchronously with said harnesses toward and past the other heddle to form an edge shed in line with said main shed;
• a rocker pivotal on said tube about said rocking axis between a pair of end positions, said doup heddle being engageable with said rocker and deflectable thereby in said weft direction in one of said end positions to one side of said ground heddle and in the other end position to the other side of said ground heddle;
• and
• means for displacing said rocker from said one end position into said other end position after deflection of said doup heddle to said one side and from said other end position into said one end position after deflection of said doup heddle to said other side of said ground heddle.

In combination with a loom having harnesses carrying an array of warp yarns defining a warp direction and displaceable in a shed direction transverse to said warp direction to form a main shed adapted to receive a weft passed through said shed in a weft direction transverse to said warp and shed directions, a leno-selvage device comprising:

• a ground heddle at an edge of said array and carrying a ground warp yarn, said ground heddle having an arm forming a support defining a rocking axis nondisplaceable in said weft direction;
• a doup heddle at said edge carrying a doup warp yarn and having an extension, said arm extending on said ground heddle away from said doup heddle;
• means for displacing one of said heddles synchronously with said harnesses toward and past the other heddle to form an edge shed in line with said main shed;
• a rocker pivotal on said support about said axis between a pair of end positions, said extension of said doup heddle being engageable with said rocker for deflection of said doup heddle thereby in said weft direction in one of said end positions to one side of said ground heddle and in the other of said end positions to the other side of said ground heddle;
• and
• means for displacing said rocker from said one end position into said other end position after deflection of said doup heddle to said one side and from said other end position into said one end position after deflection of said doup heddle to said other side of said ground heddle.
