A hand card is a tool used to clean fiber from the teeth of a wire covered roll. The rolls could be mounted in a card or be outside the card in a frame as shown in the picture. The hand card consists of two parts: (1) the metal body and handle, and (2) the insert. The insert is basically a piece of canvas with hundreds of wires sticking through it. The wires are bent so they grab fibers. Hand cards used improperly can be very dangerous. Here are a few safety tips.
- Never use a hand card on a carding machine that is being powered. Stop the machine and turn the rolls by hand.
- Never try to hand card against the wire. Always pull the hand card in the same direction the card wire teeth are pointing.
- Never leave a hand card lying on the carding machine. Put up the hand card in a safe place away from the carding machine.
- Use safety glasses when using a hand card.
Hand cards and inserts can be purchased from the vendors that sell card wire and also some carding machine and carding machine parts suppliers.
