Abstract: The thread braking device comprises a pair of braking members, which are arranged symmetrically in respect to the path of the thread. Each of the braking members has a spring member. Between these spring members a line-shaped, vertically arranged braking zone is defined. For braking, the spring members are pivoted on rockers towards the thread path. Due to this movement as well as due to the vertical arrangement of the spring members, the deposition of contaminations in the braking zone is avoided. The elasticity of the spring members reduces the danger of damage in the presence of thickened thread sections.

This mechanism also has one lifter cord passing around under the top roller of the lifter element and is fixed by each end to one of the hooks while the roller element is immovably fixed below the lifter element. The mechanism has an additional lifter cord which is fixed by one end next to the other lifter cord to one of the hooks. This lifter cord is passed around under the roller of the roller element, around over the bottom roller of the lifter element, and is extended back down, where it connected to the warp threads. The rollers are placed on shafts, which, in a horizontal plane, form an angle (.alpha.) relative to a line parallel to the direction of the knives. The roller of the roller element is placed on a shaft which, in a horizontal plane along the other side, forms an angle (.beta.

Abstract: An electropneumatic device for the automatic threading of apparatuses for feeding weft to textile machines, and a weft feeding apparatus including the device. The device has first and second ducts for feeding pressurized pneumatic fluid. The ducts are cut off by a manually-actuated valve and end in thread inlet and outlet bushes to create a pneumatic flow and a consequent suction current which entrains the thread from one end of the feeder apparatus to the other. An intermediate open channel is arranged adjacent and parallel to the drum of the apparatus to convey the pneumatic flow and the thread entrained thereby in the free portion comprised between the radial arm outlet and a thread brake. A pneumatic pusher is fed by a third pneumatic duct and is arranged at the outlet of the intermediate channel. The pusher acts on a braking device to deform it and hinder elastic action applied to the drum, so as to guide the thread entrained by the flow through the braking device.
