The document summarizes the components and operating parameters of a carding machine. It describes the objectives of carding, the machinery used including manufacturer and model. It lists the components of the carding machine and provides the technical parameters such as diameters of rollers and their speeds. It also outlines the clearance settings between parts and stop motions in the machine.

1. Carding
• Objectives • Clearance setting for

7. Clearance setting for various parts
•Licker in to feed plate – 18 TH
•Licker in to cylinder – 7 TH
•Cylinder to doffer – 4 TH
•Doffer to crush roll – 6 TH
•Licker in to combing segment – 16 TH
•Draft for the machine = 102 (approx).
•Production in kg/hr at 85% efficiency = 19.4 kg/hour

8. Stop motion for LC1/3
•Limit switch for lap tool – it stops the card in case of
shortage of lap.
•Limit switch over feed roll – it stops the card if the feeding
of double lap takes place.
•Limit switch at front panel – it stops the cylinder if the front
panel is opened.
•Limit switch over crush tool – it senses the lapping of the
crush tool.
•Full can change motion – when the can is full of slivers the
machine stops and the can is changed either by tenter or
automatically.
