Embodiment Construction

[0014] Expressed in figure 1 The weaving machine in ® comprises a number of heddle frames 1 , 2 which can be driven upwards and downwards by means of a cam system 3 . Said cam system 3 comprises control rods 4 , 5 mounted rotatably about a support shaft 6 . Each control rod 4 is connectable via a connection point 7 to a drive rod 8 , which is connectable via a second connection point 9 to a rod 11 mounted around an axis of rotation 10 . The rod 11 is connectable to a second rod 14 mounted around a rotation axis 13 via a connecting rod 12 . Each heald frame 1 , 2 is connected to the associated rod 11 , 14 via a connecting rod 15 , 16 . The rotating shafts 10 and 13 are mounted on the frame of the loom. Said heald frames 1, 2 are guided in side guides 17, 18 fitted on the frame of the weaving machine. The cam system 3 is fixedly arranged relative to the frame of the weaving machine.

[0015] Said cam system 3 also comprises a pair of cams 19, 20 for driving the heald frame ...

Abstract

A method for driving a cam system (3) for driving heddle frames (1, 2) in a weaving machine is disclosed, wherein, during a displacement (69, 79) of the central bearing shaft (6) of the cam system (3), the cams (19, 20) of the cam system (3) are positioned in an intermediate angular position (54, 56), so that the heddle frames (1, 2), during a displacement (69, 79) of the central bearing shaft (6), move virtually between an upper limit (40) and a lower limit (38) of their motional course (41). A weaving machine for the application of such a method is disclosed.

Description

technical field [0001] The invention relates to a method for driving a heddle frame (heddle frame) in a weaving machine, which contains a cam system for driving the heddle frame. The invention also relates to a weaving machine using such a method. Background technique [0002] Such a cam system of a heald frame is known, in particular from patent document US 2654397, which enables the heald frame to be driven, in particular to be leveled and de-levelled again. With the weaving machine shut down as a result of warp thread breakage, weft thread failure, or some other malfunction, said heald frames in relation to the warp threads can be leveled in one plane so that the weaver can easily detect and / or Repair disconnection or malfunction. Furthermore, leveling can also be carried out during a fabric change or some other intervention on the weaving machine. In the event of a warp thread break, after leveling, the weaver can easily determine the location of the broken warp threa...
