Minimize Wear

All parts of the knitting machine have carefully been selected and checked by Stoll. Nevertheless, they are subject to wear. You can keep the wear to a minimum if you lubricate, clean and check the machine regularly.

The following table contains an overview of the wearing parts and the possible causes for excessive wear.

Wearing parts

Wearing part

Possible causes of increased wear

Fabric take-down rollers
  • Excessive fabric take-down values
  • Contact pressure too high/low
  • Yarns harmful for e.g. abrasive, sanding yarns or yarn finishes like greases or oils
  • UV radiation (including direct sunlight)
  • Cleaning agents harmful to rubber, e.g. ether or fuels. Recommendation: Use cleaning petrol for cleaning

Belts of the fabric take-down
(Belt take-down) *
  • Too high belt speed
  • Fabric winding
  • Thread winding
  • Yarns harmful for e.g. abrasive, sanding yarns or yarn finishes like greases or oils
  • UV radiation (including direct sunlight)
  • Cleaning agents harmful to rubber, e.g. ether or fuels. Recommendation: Use cleaning petrol for cleaning

Needle brushes,
Brushes of the central lubrication
Brushes of the winding protection device *
  • Incorrect adjustment

Feed wheel rollers
  • Abrasive, sanding yarn
  • Allowing the feed wheel to run unnecessarily

Needle bed elements, cams
  • Excessive fabric take-down values
  • Yarn too thick
  • Insufficient lubrication
  • Insufficient cleaning

Yarn guiding parts (deflectors, yarn control device, etc.)
  • Abrasive, sanding yarn

Yarn carrier, yarn carrier sliding block
  • Insufficient lubrication
  • Abrasive, sanding yarn

Yarn carrier magnet
  • Magnet may not come into contact with grease or oil

Belt on auxiliary take-down
  • Following a fault on the auxiliary take-down (fabric winding device), the residual threads were not removed carefully

Belts (drive, racking, comb take-down, auxiliary take-down)
  • Belt tension too high: Danger of bearing damage (adjustment with measuring device by Stoll technician)
  • Belt tension too low: Danger of position errors (racking, auxiliary take-down)

Energy chain trailing cable
  • Heavy soiling
  • Laying down of objects
  • Damage to depositing gutter
  • Not moved into position carefully after work at the rear of the machine
