ROLLER HEAD WITH ENDLESS BELTS FOR SPINNING MACHINES Filed Nov. 28, 1932 Patented Jan. 2, 1934 ROLLER HEAD WITH ENDLESS BELTS FOR SPINNING MACHINES Charles Ggauff, Mulhouse, Haut-Rhin, France Application November 28, 1932, Serial No. 644,731, and in France December 17, 1931 2 Claims.
The present invention relates to improvements in roller heads with endless belts or sleeves, for machines used in the spinning of cotton, wool, schappe, artificial silk and other textile fibres.
A large number of roller heads with such belts have been used more or less successfully in spinning machines. They generally comprise one single driving roller for the endless belts or sleeves, supporting and feeding the textile material, said driving roller being superposed by a pressure roller to effect nipping of the textile material.
This type of roller head as all other roller heads having endless belts cannot deliver a regular product, that is to say free from swells and waists,
unless the linear speed of the belt is exactly uniform. Experience has shown that this condition is rarely fulfilled in practice owing to unequal stretching of the belts, their lack of homogeneity, particularly at the joint, and so forth, so that a less regular product is often obtained by using a roller head with an endless belt than by using one without. for the belts, there is not ensured a positive and regularmovement for the belts such as it would be necessary for realizing a regular and uniform product.
This inconvenience is completely eliminated by the roller head according to the present invention, Figures 1 and 2 of the drawing being respectively a sectional elevation and a plan of a twothread embodiment thereof.
The improved roller head comprises in addition to the feed system a two-head guide roller llapped by two endless belts or sleeves 2, the said guide roller located inside the belts being driven by two outer feed rollers 3, 4 positively driven with the same linear speed and between which it is pressed down by hooks 5 each pulled by a helical spring 6 abutting between a fixed plane 7 and a nut 8 by which the pressure of the spring may be regulated, the whole forming an elastic loading device the Indeed, with one single driving roller construction of which can however vary. This results in a very effective double drive of the endless belts or sleeves 2, which are gripped on both the outer rollers 3 and 4, thus ensuring an I? exactly uniform speed of the latter and in conse- W quence the production of a very uniform yarn. In Figuresl and 2 the plane or curved surface guiding the sleeves or belts 2 is designated by 9, the floating cylinders by 10, 11, 12, 13, 14, 15 and n 16, the slotted framework guiding the latter by 17, the tensioning rollers for the sleeves or belts by 18, the drawing rollers by 19, 20 and the textile material by 21.
Each guide roller 1 being lapped by but two endless belts, the replacement of such endless belts can be effected with great facility. The guide roller 1, the guide surface 9, the floating cylinders 10 to 16 and the tensioning rollers 18 can be rapidly removed to free the sleeves or r belts 2; for this purpose it suffices to unscrew the nut 8 of each loading hook 5.
What I claim is:-
1. In a roller head with endless belts or sleeves for spinning machines, the combination with the endless belts or sleeves of a guide roller located inside thereof, two driving feed rollers outside the belts or sleeves, said guide roller being arranged between the two driving rollers, and means for urging down said guide roller between the two driving rollers to press the belts or sleeves against both said driving rollers.
2. In a roller head with endless belts or sleeves for spinning machines, the combination with the endless belts or sleeves of two driving feed rollers and a guide roller therebetween for two endless belts or sleeves, arranged to press the latter against said feed rollers, a spring urged hook being removably connected to said guide roller and so arranged as to press the guide roller with the belts or sleeves against said feed rollers.
