Objective:

To learnt the technique of unfolding and folding of a metric chain.

Instruments:

Metric chain

Procedure:

Unfolding:

  1. Remove the strap of the folded chain and take both the handles in the left hand and hold the remaining portion of the chain in the right hand.
  2. Holding both the handles in the left hand, throw the remaining portion o f the chain  in the forward direction on the ground.
  3. Now the follower stands at the starting station by holding one handle and directs the leader to move forward by holding the other handle until the chain is fully stretched.

Folding:

  1. Bring the two handles together on the ground by pulling the chain at the center.
  2. Commencing from the center two pairs of links are taken at a time with the right  hand and placed alternatively in both directions in the left hand.
  3. When the chain is completely folded the two brass handles will appear at the top.
  4. Now tie the chain with leather strap.
