2. Load the Cover Tape

Remove the large black knob from the cover

tape spindle (loosen the brass set screw if

necessary). Remove the spring, washer, and

front plastic cover from the spindle. Place a

reel of cover tape (correct width to match the

carrier tape) on the reel center, so the tape

unwinds to the right from the bottom of the

reel. Replace the plastic cover, washer,

spring, and black knob. Tighten the knob until

there is some tension on the cover tape as it

unwinds, but make sure the tension is not

excessive. Tighten the brass set screw on the

black knob to secure it in place.

3. Load the Carrier Tape

Remove the carrier tape clamp (Fig. 2.2, Ref.

L) from the carrier tape spindle (Fig. 2.2, Ref.

K) and mount the bulk carrier tape reel on the

spindle (the sprocket holes on the carrier tape

must be on the inside). Replace the clamp

and position it so the reel is supported and

spins freely on the spindle. Trim the end of the

carrier tape so it is clean and straight.

The loading track (Fig. 2.2, Ref. P) is adjust-

able for tape width. Set the track width to

match the sealer mounted on the TM-300 by

pulling out, or pushing in, evenly on both ends

of the track. There are detents which will

cause the track to lock in at each tape width.

Open the parts cover (Fig. 2.2, Ref. Q) by lift-

ing on the black knob and remove carrier tape

guide #2 (Fig.2. 2Ref. R) by unscrewing its

black knob. Guide the carrier tape under car-

rier tape guide #1 (Fig. 2.2, Ref. N) and into

the loading track. The carrier tape should feed

through the loading track easily. Lower the

feed reel support arm if necessary to allow the

tape to feed more easily into the loading track.

Bring the end of the tape just up to cover tape

guide #3 (Fig. 2.2, Ref. S).

4. Load Tapes into Sealer

Pull the cover tape down through the cover

tape guides as shown. Pull about 12” of cover

tape out and lay it over the carrier tape, with

the free end pointing toward the sealer. The

shiny side of the tape should be up. Allow

about 2” of the free end of the cover tape to

hang over the end of the carrier tape. Push

the tapes under the cover tape guide and

through the sealer by pushing on the carrier

tape. Keep enough slack in the cover tape so

it follows the carrier tape through the sealer.

Lift the idler wheel (Fig. 2.2, Ref. E) by push-

ing down on the left side of the arm. Align the

sprocket holes in the carrier tape over the pins

on the drive sprocket (Fig. 2.2, Ref. F).

Straighten the cover tape so it is aligned with

the carrier tape and rewind any remaining

slack back onto the cover tape reel. Position

the cover tape so it is running in the groove in

cover tape guide #3. Replace carrier tape

guide #2 and screw it down. Close the parts

cover.

5. Mount Take-up Reel

Mount an empty take-up reel on the take-up

reel spindle (Fig. 2.2, Ref. H). The width of the

reel must match the width of the carrier tape

and the reel must be big enough around to

accommodate the number of components in

the taping job.

All four factors may be varied on the TM-300

but only the dwell time, seal pressure, and

temperature setting changes are usually

required. The seal width is selected at the fac-

tory and should only require changing under

unusual circumstances. The settings in the

chart are good general starting points to be

used when first learning to use the TM-300.

Experience will suggest variations from these

settings that will provide the desired seal char-

acteristics as determined by a peel force test.

Setup (cont.)

General Seal Setting Information

The cover tape peel force is determined by

four things at the time the cover tape is sealed

to the carrier tape.

These four factors are:

1. The width of the sealing track on the

heat seal shoe.

2. The pressure applied to the seal area.

3. The dwell time, or heating time that the

heat shoe is pressing on the cover tape.

4. The temperature of the seal assembly.

Approximate Starting Points for Seal Controls

***Use this chart as a guide for setting the controls for the first time. These values may need to

be altered due to variations in lot materials and customer requirements.***
