Eastman Machine Company manufactures a complete line of
marking machines, carefully designed to save time and eliminate
costly errors. Parts for these machines are readily available and
Eastman Marking Machines are serviced by the same sales and
service network that has made Eastman Cutting Machines so
popular.
HOT NOTCHER—Model HVN—Burns a perfectly true mark in knit
goods without costly raveling. No lost marks between cutting and
sewing rooms.
CLOTH DRILL MARKERS—Available with or without needle
heating attachment, 6, 8 or MVz inch drilling capacity and drill
sizes 3/64 to 3/8 Inch diameter. The solid state needle heater
heats faster, hotter and holds heat longer...completely enclosed
for operator safety.
Model CD3—The Drill Markers low profile design and telescopic
drive shaft allow accurate drilling straight down through high
layers of all types of material. The powerful motor is built to pro
vide many years of trouble-free operation.
Model CDL—The Hawk Is a lever-action cloth drill engineered by
Eastman to drill faster and better than any marking machine
made. This drill Is manufactured for tough, thick cloth like
denim, corduroy, cotton duck, broadcloth, canvas and sailcloth.
MAGNUM PUNCH PERFORATOR—The Model MP2 Magnum
Punch Perforator makes four crisp, clean holes to an inch through
as many as five thicknesses of average weight pattern paper. The
punching mechanism Is adjustable to accommodate various
thicknesses of paper. This powerful machine never misses one of
the punches. A single control lets the operator free-wheel or
single perforate.

Threadmarker
Model LTM
Operating Instructions
Care And Operation
The threadmarking machines are intended to be used for marking
pockets, etc., on lays of material such as woolens where the elec
tric drilling machines are not practicable due to the holes closing
Immediately after the drill Is removed.
THREADING THE MACHINE
Thread from spool through thread eye "C" to the thread hole "D"
in the rear of the thread cutter; then to the needle eye "H". Thread
needle from the spool side of the machine.
OPERATION OF THE MACHINE
After the material has been cut and marked with chalk, slide the
front beveled portion "F" on the threadmarker beneath the lay.
Press looper locking latch (located on opposite side) down to set
the looper. The operation of setting the looper must be performed
before every needle stroke. Pull handle "B" down until stop "J"
makes contact with the threadmarker housing. This action
releases the looper contained In the base of the machine. By
slowly retracting the needle a loop is formed and caught by the
looper. The end of the thread is held firmly by the looper and as
the machine Is withdrawn from the lay, about fifteen to eighteen
inches of thread should be stripped from the spool and cut off
with the thread cutter "E". This operation is continued until all
marked positions have been completed. Each layer of cloth Is
clipped with shears between each layer, the operator leaving
about Va to 1 inch of thread In each layer of cloth. If the thread is
clipped too short, it may fall out in subsequent handling.
TO REMOVE NEEDLE
Remove knurled cap "A" from top of machine—turn counter
clockwise to remove. Lift needle rod and needle assembly clear
from the machine. Loosen bottom set screw and remove the
needle from rod. When replacing needle and re-assembling
needle rod in machine, refer to instruction sheet #672C1-110.
OILING
Oil rod and tube at "G" twice a week.
THREAD
It is suggested that a good grade of button hole gimp be used. It
can readily be understood that, if the thread is too weak, forcing
the needle through such a great thickness of material will result
in thread breakage.
