Definitions
- the invention relates to a tensioning machine for a textile fabric with two chain tracks at the end of the infeed area of the machine, which are pivotally pivoted relative to one another about vertical axes, for endless chains deflected in the fabric inlet and outlet, which have holding means for gripping the edges of the fabric, wherein Control and drive means are provided for adapting the respective distance of the pivotable ends or cheeks of the chain conveyor facing away from the axes at the entrance of the entry field to the measured width of the respective material web to be tapered, and the pivotable chain conveyor ends by means of carrying wheels are movably mounted on a horizontal support.
- adjusting devices are provided.
- these adjusting devices have to absorb greater forces if the web between the pivotable chain web ends, which are also to be described as cheeks, is to be drawn to a predetermined output width based on an actual input width.
- the mutual spacing of the cheeks should be adapted as free of play as possible to the width of the fabric web part currently entering. For this reason, complex rack and pinion drives or chain drives (DE-AS 18 07 389).
- transverse forces to be controlled by the cheek drives i.e. the web tension across the transport direction, depend on the type of fabric to be treated.
- Fabric webs with only low transverse stability, e.g. Knitted fabrics are guided through the stenter or through the stenter with low transverse forces. Greater forces are required if the goods are to be pulled from an actual entrance width to a predetermined exit width.
- the invention has for its object to provide a transverse guide for the pivotable chain web ends or cheeks, which allows the single needle or Einkluppsch connected to the respective cheek (holding means for grasping the fabric web edges) exactly and practically without delay the more or to allow less random path of the edge of the incoming fabric web to follow without the elaborately designed and designed cross drives for the cheeks of known tenter frames would be required.
- the solution according to the invention for the tensioning machine mentioned at the outset, in which the pivotable chain track ends or cheeks are movably mounted on a horizontal support by means of supporting wheels, is that at least one supporting wheel is designed as a driven friction wheel and that a supporting motor is directly assigned to this supporting wheel .
- at least the driven carrying wheel is covered with solid rubber or the like material with a high coefficient of friction especially with respect to the carrier. If two carrying wheels are used per chain conveyor or cheek, it is sufficient according to another invention to switch a motor to the axis of one of the carrying wheels or friction wheels.
- the carrying wheels are designed as friction wheels, preferably with solid rubber tires, and if a drive motor, preferably on the friction wheel axis, is directly assigned to one of the friction wheels.
- FIG. 1 shows a plan view of the inlet field of a tensioning frame; and FIG. 2 shows a section along the line II-II from FIG. 1.
- FIG. 1 shows a top view of the inlet field of a tensioning machine.
- chain tracks 2 for endless chains 3, which are deflected around chain wheels 4 in the fabric infeed area, are shown in a scissor-like manner pivotable about vertical axes 1.
- the chains 3 have holding means 5, e.g. Needles or clips for grasping the edges 6 of the fabric web 8 entering in the transport direction 7.
- the current position of the respective fabric web edge 6 is measured essentially continuously with a width sensor 9.
- the width sensor 9 passes its measured values on to a control system for controlling drive means, with the aid of which the individual chain track 2 can be pivoted back and forth about its axis 1 in the pivoting direction 10.
- the pivoting distance between the chain track ends or cheeks 11 is adjustable.
- the position of the holding means 5 can be adapted precisely and without delay to the current position of the edge 6 of the incoming material web 8.
- the cheeks 11 are movably supported on a horizontal support 13 by means of carrying wheels 12.
- At least one of the support wheels 12 is to be designed as a driven friction wheel, and a drive motor 14 is to be spatially directly assigned to this support wheel 12.
- Wheels which are preferably provided with solid rubber 15 can be considered as carrying wheels 12.
- two carrying wheels 12 are provided per cheek 11, both of which are preferably to be designed as rubber tires with rubber tires.
- the friction wheel to be used according to the invention is preferably constructed from a metallic core (for example a rim) with a vulcanized-on elastomer for converting the torque of the connected drive motor into a frictional force between the friction wheel and the carrier.
- a motor 14 is preferably placed on the axis of one of the support wheels 12 of each chain conveyor 11. The following are preferred as motors: helical geared motors, bevel helical geared motors, worm geared motors and helical worm geared motors each with three-phase or direct current operation.
- the respective motor 14 is controlled by regulating and control means, not shown, but which are readily accessible to the person skilled in the art, as a function of the measurements of the associated width sensor 9.
- Light sensors with point-like scanning of the goods edge but also mechanically with electrical contacts, are used to detect the goods edge.
- light sensors with an analog range are preferably used in order to be able to readjust the cheeks at high speed of the goods edge.
- contactor controls or contactless switching thyristor switches are possible as control means for the motors.
- frequency converters for 4-quadrant operation are preferably used together with three-phase motors.
- a tensioning machine for a textile fabric web is described with two chain conveyors which are pivotally pivotably mounted in the infeed area of the machine and in which chains with holding means for gripping the fabric web edges run.
- the free ends or cheeks of the pivotable chain track ends are movably supported on a horizontal support by means of supporting wheels.
- at least one support wheel is designed as a driven friction wheel and a drive motor is directly assigned to this support wheel.
