Method and equipment for Jacquard selection in a textile machine

An equipment for Jacquard selection in a knitting machine, including:

• at least one needle bed equipped with mobile parts for the formation of fabric;
• at least one selector means for selection of said mobile parts;
• at least one counteracting member which counteracts action of said selector means;
• at least one raising cam for moving the selected mobile parts;
• characterized by a pre-selection cam for moving said mobile parts within the needle bed in a pre-selected position, said selector means causing the selected parts to move outside said needle bed, under the action of said counteracting member, in order to co-operate with said raising cam, said pre-selection cam being arranged upstream of said selector means with respect to relevant movement between said selector means and said pre-selection cam and said needle cylinder.

A method for Jacquard selection in a textile machine, the method including the steps of:

• providing a needle bed with a plurality of mobile parts for formation of fabric, said mobile parts being movable between an inner and outer position with respect to said needle bed;
• biasing said plurality of mobile parts toward said outer position;
• sequentially moving all of said plurality of mobile parts past a preselection cam to move said plurality of mobile parts towards said inner position;
• moving said plurality of mobile parts past a selector after said sequential moving;
• selectively operating said selector for passing individual ones of said plurality of mobile parts into said outer position by said biasing;
• raising said individual ones of said plurality of mobile parts by a raising cam, said selective operating of said selector blocking non selected individual ones of said plurality of mobile parts from engagement with said raising cam.
