Filed: 1986-01-08
Abstract: PURPOSE:To prevent a ribbon winding without lowering productivity by turning on or turning off a motor for driving a traverse drum only in the vicinity of a package diameter in danger of generating a ribbon, when winding thread round the package. CONSTITUTION:Running thread is wound round a package P while making traverse by means of a traverse drum 1. the traverse drum 1 is driven by a motor Mn. When the winding of thread advances, the package enlarges its diameter like P3 or P4. When the diameter grows larger a cradle arm 3 rotates in the arrow A direction round an axis 2 and a fan-shaped winding diameter instructing member 4 rotates in the arrow B direction through rink mechanism 6, 7, 8. Iron pieces t1-t4 are fixed to the periphery of a fan 4, corresponding to a diameter in danger of the package P generating a ribbon. Only while a magnetic sensor Sn is output the motor Mn is turned off through a control circuit Rn. Hereby the occurrence of the ribbon is easily prevented without lowering productivity.

Abstract: PROBLEM TO BE SOLVED: To shorten an inter-pump surface size by rotatably housing an impeller fixed on a main shaft in an impeller chamber, and also connecting an elbow provided with straightening impellers inside to a just downstream side of the impeller chamber. SOLUTION: An impeller 2 fixed on a main shaft 1 is rotatably housed in an impeller chamber 3, and also an elbow 7 provided with a plurality of rectified impellers inside is connected to a just downstream side of the impeller chamber 3. The main shaft 1 extends upward by rotatably and water tightly penetrating the elbow 7, and it is connected to a primary motor. At this time, the curvature of the elbow 7 is reduced, and a curvature radial R is set to a larger level, and thereby, an inter-pump surface size H between the inlet of the impeller 2 and the center line of the horizontal direction of the elbow 7 can be shortened sharply. It is thus possible to release differential performance of arrangement by constraint on a size, and also it is possible to reduce hydraulic power loss in the elbow part.
