Abstract
A long spinning machine, preferably a ring spinning machine, with a plurality of drawing means, which serve to draw the fiber strands with the drawing means being arranged adjacent to each other and extending lengthwise of the machine the drawing lower rollers of the drawing means formed by a plurality of long roller lines positively connected together at one point by drive gear transmissions which provide predetermined rpm ratios between the roller lines with some of the roller lines connected together by additional drive gear transmission at least at one additional point spaced from the one point to eliminate or substantially reduce torsion in the roller lines.
Claims21
A long spinning machine, preferably a ring spinning machine having at least one drive motor with a plurality of drawing means which serve to draw the fiber strands that are arranged next to each other at least on one side of the machine, with the driving lower rollers of each drawing means being formed by long roller lines, each of which roller lines extends along all of the drawing means of the long side of said machine, and further that the roller lines arranged on said long side of the machine are positively connected to each other at one point along the roller lines by drive gear transmissions thereby correlating the rpm relationships of the roller lines, the further improvement in which at least some of the roller lines of the drawing system that are arranged on the long side of the machine are positively connected with each other at least at one additional point spaced from said one point along the roller lines by additional drive gear transmissions and wherein all of said drive gear transmissions connected to the same roller lines have the same gear ratios and wherein the roller lines associated with the drawing fields having the greatest draft are connected with each other by a plurality of said drive gear transmissions.
A spinning machine, comprising a ring spinning machine, with a plurality of drawing means which serves to draw the fiber strands in which said drawing means are arranged next to each other at least along one side of the machine, the lower rollers of which are formed by long driving roller lines that are connected to each other by drive gear transmissions, further wherein said drive gear transmissions which connect the roller lines are arranged medially of the drawing area of said spinning machine.
A spinning machine, comprising a ring spinning machine, with a plurality of drawing means which serve to draw the fiber strands which are arranged adjacent to each other on at least one side of the machine, further including driving lower rollers, each of which extends along all the drawing means of the long sides of said machine with the roller lines on one side of the machine being connected to each other by drive gear transmissions to thereby correlate the rpm ratios of the roller lines, further wherein at least one of said roller lines arranged on the long side of the machine concerned has a booster motor, which exerts a driving torque on said roller line at a distance from the drive gear transmissions to thereby reduce torsion therein during operation.
