摘要:
improvements are made to members of a loom dobby control unit so as to allow structural separation between the reading unit and control unit. For this purpose, the reading unit rockers operate on the control unit by simple bearing and thrust contact with the horizontal needles which control the hook lifting rods. Moreover, the lifting blades for said rods are controlled together with the hook lowering plates by the motion of shafts which control the dobby knife oscillations.

An improved dobby uses linkages for controlling the oscillations of the fixed and mobile knives about their axes which comprise first levers fixed to the knives, second levers fixed to control shafts, and connecting rods which link said first and second levers together to form an articulated parallelogram. In this dobby, the hook operating rods are controlled by the same shafts which control the knife oscillations, by means of an articulated joint.

Improved means are provided in a loom dobby for taking-up play in the control unit. The surfaces of the fixed and mobile blades which limit the stroke of the rocker arms in this unit are positioned perpendicular to the line joining the points of contact between the dobby hooks and knives to the mean points of contact between said blades and the rocker arms. Moreover, said surfaces are concave in the fixed blades and convex in the mobile blades. The linkage which cause the mobile knives to oscillate are in the form of false articulated parallelograms.
摘要:
A single rod hook for a double-lift, open-shed jacquard weave machine of the type comprising mobile grippers which intersect each other, has its upper nibs formed as the two teeth, with their facing surfaces inclined, of a single bifurcated projecting appendix in which they join together at the same height. Said appendix is disposed in a diametrically opposite position to the lower nibs. A jacquard weaving machine using hooks of the aforesaid type has its hooks controlled with a composite movement of rotation and flexure.

in a feed device for the punched paper tape carrying the coded fabric design for loom shed formation dobbies, the punched tape roller spindle can be disengaged from one of its end supports and can rotate with the other of said supports to enable the punched tape to be fitted, replaced or extracted, without interrupting the connection between the drive means and punched and punched tape roller.
