Abstract
A double-lift weave system comprising a plurality of hooks, each of which is provided with two arms mounted on a base and each of which includes a lift lip adapted to cooperate with one of the knives of two griffe frames moving in phase opposition in a reciprocating movement. The position of each lip is controlled in order to be selectively moveable with respect to a knife by an actuator disposed between the two arms. Each hook further includes two open shed heels which are controlled by the actuator and adapted to cooperate with open shed bars so as to be moveable with respect to the bars. The system is particularly applicable to weaving looms.
Claims18
A double-lift weave system for a weaving loom, the weave system comprising:
- a plurality of hooks each having two arms extending from a base, each arm including a lift lip adapted to be selectively engageable with a knife of a griffe frame,
- an actuator disposed between said arms for moving said arms to selectively position said lift lips thereof from a first position wherein said lift lips are free of engagement with a knife to a second position wherein said lift lips are engageable with a knife, each hook further including two open shed heels adapted to be selectively engageable with open shed bars spaced on opposite sides of said hooks, said open shed heels being controlled by said actuator so as to be moveable from a first position spaced from the open shed bars to a second position wherein said open shed heels are engageable with the open shed bars.
In a weaving loom having at least one heddle frame connected to hooks which are moved by selective engagement with knives carried by two grille frames which move in phase opposition in a reciprocating manner, the improvement comprising:
- each of said hooks having two arms extending from a base, each arm including a lift lip adapted to be selectively engageable with a knife of one of the grille frames,
- an actuator disposed between said arms for moving said arms to selectively position said lift lips thereof from a first position wherein said lift lips are free of engagement with a knife to a second position wherein said lift lips are engageable with a knife, each hook further including two open shed heels adapted to be selectively engageable with open shed bars spaced on opposite sides of said hooks, said open shed heels being controlled by said actuator so as to be moveable from a first position spaced from said open shed bars to a second position wherein said open shed heels are engageable with said open shed bars.
