摘要:
A yarn-selecting device of a knitting frame comprises a mechanism for joig the yarn being knitted to a selected yarn to be knitted, which mechanism comprises a swivelling finger for forming a closed loop of the yarn to be knitted. Two levers form an open loop of the yarn being knitted and insert it through the closed loop of the yarn to be knitted on the finger. A hooking lever is provided for pulling the yarn to be knitted through the open loop of the yarn being knitted, after which the open loop-forming lever is retracted thus removing the closed loop from the finger, and the yarn being knitted is cut by a knife while the end of the yarn to be knitted is released from a gripper.

The yarns to be selected are mounted on a selecting rocker pivoting about an axis and are held by a clipper. The yarn is selected by this rocker and is raised by a lever. A finger performs two turns and forms a closed loop of this yarn. An arc-shaped rod which is integral with an arm mounted so as to oscillate about a shaft brings the yarn being knitted into the open end of the finger. A hook takes the closed loop of yarn while oscillating about a vertical shaft and returning to its initial position. It releases this loop and grips the yarn being knitted which is then cut by the clipper actuated by a finger which is integral with the arm and engages with a cam integral with the axis of the clipper. At the same time, the selected yarn is freed by this clipper.

摘要:
The invention concerns an external gear hydraulic pump including a pump body housing rotating pinions that mutually engage. Located on opposite sides of the body are a cover and a support, forming an outlet manifold for high pressure fluid. Acoustic insulation elements damp the vibrations produced by the pinions. The acoustic insulation elements acoustically decouple the pump body from the support.
