How to make up the plastic work clamp

The cassette type work clamp is composed of cassette plate
(U), cassette plate (D), and the hinges as illustrated in the
left figure.
1. Cut out cassette plates (U) and (D). For cutting dimen-
sions, refer to section "How to make up the clamping
type work clamp".
* Making up two cassettes to use them alternately will
increase work efficiency.
2. Bond a paper cushion material or the like around the cut-
out section to firmly press a material to be sewn.
Cassette plate (D) is available in two types; D-A and D-B.
* Use cassette D-B with the same way as D-A, except
that a plastic plate or the like must be bonded on the
back of D-B. When mounting hinges on cassette plate
D-B, insert a countersunk screw M3 into the 4.6 mm
diameter countersunk hole prior to bonding the plastic
plate.
