This invention relates to a device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement whereby the device comprises a rod mechanism (2, 3, 4) of which a first (2) and a second rod (3) are rotatably connected to respectively the aforesaid body (1) and a fixed part (11), whereby this rod mechanism is provided in order to exert a rectilinear movement on the joint (5) between the body (1) and the first rod (2) in the course of driving the body (1). The joint (5) between the first rod (2) and the body (1) moves for that purpose preferably in a straight line through the joint (7) between the second rod (3) and the fixed part (11). This device is especially utilized as shed-forming device of a machine of the Jacquard type for the rectilinear guiding of knife-supporting beams. Such a rectilinear guide has the advantage that it can be implemented with only hinge points that require no maintenance.
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement, characterized in that the device comprises a rod mechanism (2, 3, 4) of which a first (2) and a second rod (3) are rotatably connected to respectively the aforesaid body (1) and a fixed part (11), and that this rod mechanism (2, 3, 4) is provided in order to exert a rectilinear movement on the joint (5) between the body (1) and the first rod (2) in the course of driving the body (1).
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement according to one of the preceding claims characterized in that the first rod (2) is rotatably connected in a first joint (5) on this first rod (2) to the body (1), that the second rod (3) is rotatably connected in a first joint (7) on this second rod (3) to the fixed part (11), that the aforesaid first (2) and second rod (3) are rotatably connected to each other in a common second joint (6) so that the distance (a) between the first (5), (7) joints of the first (2) and the second rod (3) and the second joint (6) for both rods (2), (3) is equal, and that means (4) are provided to determine the positions of the rods (2), (3) during the movement of the body (1) so that angle (α2) between the first rod (2) and a plane perpendicular to the direction of movement is always equal to the angle (α1) between the second rod (3) and a plane perpendicular to the direction of movement.
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement according to one of the preceding claims characterized in that the rod mechanism comprises only hinge points.
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement according to one of the preceding claims characterized in that the back and forth movement is an almost vertical movement.
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement according to one of the preceding claims characterized in that the aforesaid shed-forming device is a device of a machine of the Jacquard type.
Device for the rectilinear guiding of a body (1) of a shed-forming device that can be driven in a go and fro movement according to one of the preceding claims characterized in that the aforesaid body (1) is a knife-supporting beam.
Drive system for knife-supporting beams characterized in that the system is provided with a guiding device according to one of the preceding claims.
Jacquard machine characterized in that it is provided with at least one knife-supporting beam working together with a guiding device according to one of the preceding claims.
