Abstract
The invention concerns a frame comprising two posts (4, 4′) and two cross-members (6, 6′), a catching member (8, 8′) adapted to receive one corresponding end of at least one heald (10), and damping means (12, 12′) against which at least one end of the heald is urged to be pressed. At least when the frame is stationary, the heald being substantially rectilinear, when one first end of the or each heald (10) is pressed, either on a first catching member (8) at the traction zone (S1) thereof, or on a first damping means (12) at the compression zone (C1) thereof, the other end of the or each heald (10) is pressed, either on other damping means (12′) at the compression zone (C′1) thereof, or on another catching member (8′) at the traction zone (S′1) thereof.
Claims16
A heald frame for a weaving machine, the frame comprising two posts, two cross-members and at least one damping means, each cross-member being provided with a catching member for engaging an adjacent end of at least one heald of the frame, the at least one damping means being mounted to at least one of the cross members or at least one of the catching members, said at least one heald having first and second ends, each of said first and second ends having a compression zone and a traction zone that are in a spaced relationship relative to one another, such that when said frame is in a stationary state and when the at least one heald is substantially rectilinear, the compression zone of the first end of the at least one heald bears against an opposing area of contact of the at least one damping means and the traction zone of the second end of the at least one heald bears against an opposing area of contact of a first adjacent catching member such that the compression zone of the first end and traction zone of the second end simultaneously bear against an opposing area of contact of the at least one damping means and an opposing area of contact of the first adjacent catching member, respectively.
A weaving machine, the weaving machine comprising at least one heald frame, the heald frame comprising two posts, two cross-members and at least one damping means, each cross-member being provided with a catching member for engaging an adjacent end of at least one heald of the frame, said at least one heald having first and second ends, each of said first and second ends having a compression zone and a traction zone that are spaced relative to one another, such that when said frame is in a stationary state and when the at least one heald is substantially rectilinear, the compression zone of the first end of the at least one heald bears against an opposing area of contact of the at least one damping means and the traction zone of the second end of the at least one heald bears against an opposing area of contact of a first adjacent catching member such that the compression zone of the first end and traction zone of the second end simultaneously bear against an opposing area of contact of the at least one damping means and an opposing area of contact of the first adjacent catching member, respectively.
