Carpet making machinery

Carpet making machinery including a support and movement means to support and move a backing material web through a pile forming station in first discrete steps in a first direction, at least one needle head supported on one side of said pile forming station for movement in a second direction transverse to said first direction between one lateral region and a second lateral region whereby a needle of the or each said needle head carrying yarn penetrates said backing material web at a plurality of locations and with cooperation of a loop forming head on the other side of said pile forming station forms a plurality of yarn loops on one face of the backing material web, the or each said needle head carrying a plurality of said needles whereby each said needle is selectably movable from a non operative position into an operative position, each said needle in use having a separate yarn supplied thereto, the or each said needle head including a carriage member rotatable about an axis parallel to said needles with said needles being radially spaced from said axis, said carriage member being arranged upon rotation to move each said needle to a said operative position.

Carpet making machinery including a support and movement means to support and move a backing material web through a pile forming station in first discrete steps in a first direction at least one needle head supported on one side of said pile forming station for movement in a second direction transverse to said first direction between one lateral region and a second lateral region whereby a needle of the or each said needle head carrying yarn penetrates said backing material web at a plurality of locations and with cooperation of a loop forming head on the other side of said pile forming station forms a plurality of yarn loops on one face of the backing material web, the or each said needle head together with an associated said loop forming head, being mounted to selectably move in at least said second direction while also being selectably movable in said first direction.

Carpet making machinery including a support and movement means to support and move a backing material web through a pile forming station in first discrete steps in a first direction, at least one needle head supported on one side of said pile forming station for movement in a second direction transverse to said first direction between one lateral region and a second lateral region whereby a needle of the or each said needle head carrying yarn penetrates said backing material web at a plurality of locations and with cooperation of a loop forming head on the other side of said pile forming station forming a plurality of yarn loops including at least one looper element and a loop cutting mechanism, the or each said needle head carrying a plurality of said needles whereby each said needle is selectably movable from a non-operative position into an operative position, each said needle in use having a separate yarn thereto.

Carpet making machinery including a support and movement means to support and move a backing material web through a pile forming station in first discrete steps in a first direction, at least one needle head supported on one side of said pile forming station for movement in a second direction transverse to said first direction between one lateral region and a second lateral region whereby a needle of the or each said needle head carrying yarn penetrates said backing material web at a plurality of locations and with cooperation of a loop forming head on the other side of said pile forming station forming a plurality of yarn loops including at least one looper element and a loop cutting mechanism, the or each said needle head carries a plurality of said needles whereby each said needle is selectably movable from a non-operative position into an operative position, each said needle in use having a separate yarn supplied thereto, said machinery further including yarn drive means adapted to positively deliver predetermined lengths of a said yarn from an at least semi continuous yarn supply to the or each said needle of the or each said needle head, said predetermined lengths of a said yarn being selectably adjustable.

Carpet making machinery including a support and movement means to support and move a backing material web through a pile forming station in first discrete steps in a first direction for forming pile on said backing material web, said pile having opposed first and second lateral regions, at least one needle head supported on one side of said pile forming station for movement in a second direction transverse to said first direction from said one lateral region to said second lateral region whereby a needle of the or each said needle head carrying yarn penetrates said backing material web at a plurality of locations and with cooperation of a loop forming head on the other side of said pile forming station forms a plurality of yarn loops on one face of the backing material web, the or each said needle head being driven from said second lateral region to said one lateral region without operation of a said needle of the or each said needle head.
