Definitions

  • each roller functions as the windup roller and the other as the wind-off roller, and their function reverses during each subsequent rewinding operation.
  • An infinitely variable friction drive cooperates with each winding roller.
  • Each friction drive incorporates a drive disk and a driven or power takeoff element, for instance in the form of a pivotably and rotatably mounted spherical segment.
  • Regulator means serve to automatically control the friction drives in accordance with the progression of the winding operation, such regulator means being controlled by the changes in the web-length appearing between the winding rollers.
  • the spherical segments can be pivoted by the regulator means through the same angle in order to selectively vary the point of contact of each drive disk at its associated spherical segment, and to thus also fulfill certain required proportionality relationships between the radii of the circular path of travel of the drive disks and the associated radii of the wound package of material.
  • the present invention relates to an improved rewinding I machine or apparatus for the single or multiple rewinding of weblike material, especially fabric webs.
  • Euniformor constant tension of the material during the rewinding operation at the jigger is, however, also important for sublsequent processing, because, for instance, with fluctuating .tension, wound up webs of material have an irregular width [which leads to skeins'or hanks with uneven side surfaces.
  • Another more specific object of the present invention relates toan improved rewinding machine which insures for a constant web velocity and tension, even when working with ver sensitive webs of material, and while employing the simplc sttechnical, economical and reliable construction for such apparatus.
  • Still a further noteworthy objectof this invention relates to anlimpro'ved rewinding machine of the aforementioned type which is extremely reliable in operation, relatively uncomplicated in structure and economical to manufacture and not readily subject to breakdown.
  • the inventive rewinding a'pparams for the single or multiple rewinding or weblike material from one driven winding roller to another driven winding roller, and vice versa, whereby the rewinding drive occurs by means of a drive motor via a respective infinitely variable friction drive associated with each winding roller.
  • a control device which is regulated or controlled by the changes in the web-length between the winding rollers.
  • each of the two friction drives whichare of the same construction consists of a drive disc and a driven or power takeoff element formed by a spherical segment.
  • the power takeoff element is pivotable'about the geometric axis of the spherical segment which axis is perpendicular to the plane containing the shaftmember for the drive discs and is rotatable about a shaft member situated in this plane.
  • the rotational axes of both power takeoff elements are always guided parallel to one another.
  • the point of contact between the drive disc and power takeoff element at both friction drives is selected such that the radius from the'piuot axis of the power takeoff element to this point of contact in the mentioned plane encloses an angle of +45 with a perpendicular connecting line between the pivot axis and the drive disc shaft in this plane at one friction drive, and at the other friction drive encloses an angle of 45.
  • both power takeoff elements are pivoted through the same angle in accordance with the takeup of material through its path of travel, and thereby the relationship or ratio of the radii of the circular path of travel of both drive discs driven with the same speed and the power takeoff elements associated therewith is always maintained proportional to the relationship or ratio of the associated radii of the wound package,

  • This web of material B is unwound from a first driven winding roller la onto a second driven winding roller 1b and then unwound in the reverse direction and, in known manner, is conducted between both rollers 10 and lb through a suitable treatment liquid located in a nonillustrated vat or the like.
  • the web of material B is guided or trained about a pendulum or floating roller 31 secured to one arm of a lever member 32, the pivot point of which is designated by reference numeral 33.
  • the desired tension of the web of material B between both of the winding rollers la and lb is adjustable by means of a cylinder unit 34 acting upon the lever member 32.
  • the momentary or instantaneous radii of the web of material 8 wound upon both winding rollers la and 1b are designated by reference characters Ra and Rb (FIGS. 3 through Driving of both winding rollers la and 1b takes place by means of a suitable drive motor 35, which is common to both winding rollers la and 1b, and which drives a shaft member 38 through the agency of the bevel gears 36 and 37.
  • a suitable drive motor 35 which is common to both winding rollers la and 1b, and which drives a shaft member 38 through the agency of the bevel gears 36 and 37.
  • Two similarly constructed drive plates or discs 2a and 2b are mounted upon the shaft member 38. Each of these drive discs 2a and 2b forms a respective member of two friction drives for driving the winding rollers la and lb.
  • Each of these drive discs 20 and 2b cooperates with a power takeoff element 30 and 3b, respectively, possessing the form of a spherical segment.
  • a respective radially extending shaft 40 and 4b is secured to the inner surface of each spherical segment 3a and 3b, respectively. More specifically, these shafts 4a and 4b are mounted in such a way that they are situated in a plane which also contains the shaft member 38. In FIG. 1 this plane coincides with the plane of the drawing.
  • these shafts 4a and 4b each extend within a respective tubular member or pipe 5a and 5b, and are rotatably mounted therein at the bearings 6a and 6b, respectively.
  • These tubular members 5a and 5b are each carried by a transversely extending tubular member 7a and 7b, respectively (FIG. 2), these tubular members 7a and 7b thus extending perpendicular to the previously mentioned plane.
  • the central axis of each tubular member 7a and 7b passes through the center of the associated power takeoff element 3a and 3b, respectively.
  • both of the tubular members 70 and 7b are rotatably mounted at the frame or housing 39 (FIG. 2) of the illustrated apparatus, so that each of the power takeoff elements 3a and 3b is pivotable about its diameter which is perpendicular to the previously mentioned plane containing the drive shaft 38 for the drive discs 2a and 2b.
  • respective shaft members 8a and 8b are mounted in the tubular members 7a and 7b, respectively, at the bearings 9a and 9b, respectively.
  • a respective bevel gear 10a and 10b is seated upon the shaft members 80 and 8b.
  • the bevel gears 10a and 10b mesh with the bevel gears 11a and 11b, respectively, seated upon the shaft members 40 and 4b, respectively.

  • a rod member 43 which opcrably interconnects both power takeoff elements 3a and 3b with one another it is thus possible by means of the control device 42 to vary through the same angle the pivotal position of both spherical segments 3a and 3b about their associated pivot axes (defined by members 7a and 7b) and thus, as will be explained more fully hereinafter, to change the momentary circular path of travel of the drive discs 2a and 2b at their associated spherical segments 3a and 3b, respectively.
  • Actuation of the control device 42 takes place in known manner through the agency of a rod member 44 engaging with the lever member 32.
  • a precondition or prerequisite for a unifonn tension and speed of the fabric web B during its throughpassage through the treatment liquid during a rewinding operation is that there occurs a change in the driving speed or velocity of the rollers la and lb in accordance with the changing radii Ra and Rb of the material carried on these rollers la and lb, respectively.
  • F and F represent the areas of the end surfaces of the fabric wound upon the respective winding rollers.
  • n represents the momentary speed of rotation of the left winding roller and n the momentary rotational speed of the right winding roller (FIG. 3). From this relationship it is possible to derive the following equations:
  • the momentary peripheral velocity at both contact locations A of the power takeoff element 3a and A of the power takeoff element 3b are equal and amount to:
