1 DESCRIPTION OF THE MACHINE The Computerized Folding Machine COM52 manufactured
by COMELZ and outlined in picture 1, is used to fold and at
the same time cement the edge of leather components and
other materials of similar nature.
The operator guides the component piece against a guide
and under a creaser foot that holds the material and
spreads the cement.
Twin hammers fold, press and feed the component.
2 PROTECTIONS USED FOR SAFETY PURPOSES, picture 2
A) Handling
The low weight of the machine does not cause
handling problems.
Correct procedures to handle the machine are
described in chapter 5.
B) Use
Covers fixed to the frame with screws protect from
electrical and mechanical hazards.
•The container for the high temperature cement
is located on the back of the machine, far from
the operator. Covers A - B - C prevent the
operator from unintended contact with the hot
container.
Caution! Cover C gets hot during operations and must be opened very cautiously.
Caution! The operator must guide the work-piece very near the creaser foot that spreads the cement and has
a working temperature of 120-140 degrees.
Caution! Never use the machine without its covers.
C) Maintenance
Specific preventive maintenance servicing is not necessary.
Caution! Maintenance servicing, for its very own nature, might be necessary when the machine does not work
correctly. For this reason, as a rule during maintenance operations, it is extremely hazardous to rely on the
correct functioning of safety devices, even when they appear to be perfectly working.

4 INTENDED AND UNINTENDED USE OF THE MACHINE
The COM52 machine was designed to fold and cement the edge of leather pieces and other materials with
similar features. It is commonly used to manufacture shoes, leather-ware and leather garments.
Unconventional use can cause serious injuries to the operator and damage the machine.
5 HANDLING AND TRANSPORTATION
Skilled personnel with adequate equipment to deal with its
dimensions and weight must perform the lifting and
transportation of the machine.
The machine must be secured as indicated in picture 3.
6 INSTALLATION OF THE MACHINE
6.1 OVERALL DIMENSIONS
The overall dimensions of the COM52 folding
machine are shown in picture 4.
6.2 REQUIRED CLEARANCE
Position the machine to leave enough clearance to allow
servicing, as shown in picture 5.

6.3 ENVIRONMENT
•Do not place the machine in rooms with explosion or fire hazard.
•Shelter the machine from bad weather.
7 PREPARATION OF THE MACHINE FOR THE INSTALLATION
7.1 CLEANING AND INSPECTING
•Make sure that the various components of the machine were not damaged during transportation and
handling.
•Accurately clean the machine from dust and smearing substances, if any.
•Make sure the machine lays flat on the floor. Level the machine through its adjustable foot, picture 6, if
necessary.
7.2 ELECTRICAL CONNECTION
•Make sure the voltage and frequency values of the machine, indicated on a label on the back of the control
unit near the power supply cable input, picture 6, match those of the mains. Then connect the machine
through its cable.
The voltage of the machine is fixed and cannot be changed.
Important! The machine is single phase.
•maximum electrical consumption 600 W
•medium electrical consumption 350 W
•allowed tension +/- 10 of the rated voltage
7.3 OIL FILLING
•Remove the cover, picture 6.
•Fill the oil sump of the machine through the plug up to the mark on the oil window, picture 6.
The oil level must not exceed the red mark.
•Use SAE10 viscosity lubricating oil.
8 INSTALLATION OF THE MACHINE

The machine can store in memory the parameters for 99 types of
folding.
When the machine is turned on, the D5 display shows a number
that indicates the selected folding style.
T14 and T15 - To select one recorded folding style.
D5 - It shows the selected folding style.
Memorized parameters
For each of the 99 folding styles the machine stores in memory the
data input received from the touch-pad, from the following sections:
•Cement (except overall temperature)
•Feed rate: outside corners, straight edges, inside corners
•Photocells
•Folding members: creaser foot, width guide, lip turner
•Operation mode: feed, cement, creaser foot, knife
8.6.2 CEMENT, picture 8.
8.6.2.1 Pot temperature
T16 - To select the cement pot temperature.
Press repeatedly to select.
Standard temperature is 140 degrees C.
D8 - It shows the pre-set temperature.
D6- It shows the actual pot temperature.
The setting of this parameter is generally
valid for all recorded folding styles.
8.6.2.2 Creaser foot temperature
T17-T18 - To adjust the temperature of the
cement spreading foot.
D7 - They show the pre-set temperature.
Standard adjustment is obtained with 2 - 4
lights on.
8.6.2.3 Flow rate
T19-T20 - To adjust the quantity of cement.
D9 - They show the pre-set quantity.
Standard adjustment is obtained with 3 - 5
lights on.
8.6.2.4 Delay
T21-T22 - To delay the start of cement
application, when required, leaving a dry bit at
the start.
