Definitions

  • Hard web rolls are undesirable, particularly if the web roll consists of certain types of fabrics. This is particularly true of cord fabric with a loose weft, as is used in the manufacture of tires. However, the hardness of the web roll should conform to the weight and to certain characteristics of the material, since a predetermined winding density is required.
  • a disadvantage of known winding apparatus of this type is that very smooth material, such as nylon, slips relative to the single drive roller so that the web is not properly wound up.
  • Another object of the invention is to provide a windup apparatus in which the web is reliably wound up on a core, even if the web consists of a very smooth synthetic yarn, such as nylon.
  • a further object of the invention is to obtain a predetermined uniform winding density of the web roll, which is not influenced in an undesirable manner by additional pressure required for driving the web roll.
  • the present invention comprises a pair of drive rollers mounted on carrier means turnable with the same about a common shaft.
  • One embodiment of the invention comprises bearing means supporting a winding core for rotation about a.
  • core axis a pair of drive rollers for frictionally engaging and winding up a web on the core
  • carrier means supporting the drive rollers
  • supporting means supporting the carrier means with the drive rollers for angular movement about a carrier axis parallel to the core axis, and also for movement with the supporting means toward and away from the core axis.
  • the pressure and frictional engagement between the drive rollers and the wound up web depends on the action of the adjustable motors on the arms, and the motors are adjusted by control means depending on the angular position of the pair of arms, which is preferably signalled by a potentiometer.
  • a regulating unit controlling a pressure valve which controls one or more hydraulic systems or similarregulating systems controlling the adjustable hydraulic motors which operate the swing arms to press the drive rollers against the wound up web.
  • the contact pressure between the drive rollers and the web roll can be controlled in a predetermined manner, for example by decreasing, maintaining constant, or increasing the pressure between the drive rollers and the web.
  • the contact pressure exerted by drive rollers on the web roll can therefore be varied in a predetermined manner depending on the radius of the wound up web roll as required for the specific web roll which is being wound up.
  • Hydraulic motors are used which are connected with the carrier means to angularly displace the same relative to the swing arms.
  • the carrier means are preferably a pair of bearing flanges supporting the drive rollers, and being pivotally mounted on the swing arms.
  • the contact pressure exerted by the drive rollers on the wound up web can be additionally varied by means of this hydraulic system.
  • the finished web roll can easily roll down the ramp to a support on which it rests.
  • the carrier axis of the bearing flanges in the pair of swing arms is spaced a greater distance from the support than the axis of the winding core.
  • the greater part of the weight of the web roll acts on the drive roller closer to the support than on the other drive roller, and this causes an angular movement of the carrier means or bearing flanges about the carrier axis on the swing arms so that the other drive roller farther spaced from the support, urges the web roll to move over the first roller onto the discharge ramp.
