3.2 Application and functions 

HM-4200 is a carton sealer with automatic top flap sealing of folding cartons by use of hot melt. The 

carton sealer has a capacity of 12-15 cartons per minute dependent on the construction of the carton 

and the cardboard quality. The machine has a compact design and is easily adjusted for variable carton 

sizes. Manual adjustment of side and top drives. 

The bottom sealed carton is led into the carton sealer, the flap bow folds the front and rear flaps of the 

carton, the side drives lead the carton forward for folding of the side flaps and towards the hot melt gun 

that applies the glue. The carton is then led out of the machine.

5. Operation 

5.1 Start-up 

Turn the regulator button (10) clockwise until the working pressure on the manometer (9) shows 5-6 bar. 

The button must be pulled out before it can be turned. In this position, the flap bow swings upwards. 

5.2 Setting of formats 

Width adjustment 

Place the carton at the inlet end, approximately opposite the side drive pillars. Loosen the handle for 

locking of side drives (6). Move the side drives towards each other until there is a light pressure on the 

carton. Tighten handle. 

Height adjustment 

Place the carton in the machine, move the side drives to their outermost positions and adjust the height 

by means of handle (8) for adjustment of pillar up/down. 

Side flap closing arrangement 

Adjustment of the side flap closing arrangment at each side is carried out on the finger grips (12) placed 

on the top part of the machine above the side flaps. 

Length adjustment 

Adjust the flap bow for rear flap bending by adjusting the infeed stop (13) and the flap bow finger grip 

(11). Adjust the flap bow lengthwise by loosening the finger grips (11). Pull out the finger grips when 

operating with long cartons. 

Adjust the infeed stop (13) roughly so that the distance between flap bow and infeed stop approximately 

equals the carton length (a little more at wide cartons and a little less at narrow cartons). Readjust after 

the first carton. 

Flap bow 

Adjust the up/down movement of the flap bow on the finger grips (11). See pneumatic diagram for 

throttling of valve. 

5.3 Glueing 


On delivery, the length of the glue lines are preprogrammed corresponding to the sample cartons sent. 

If new lengths of the glue lines are required, or if new carton formats are added, check the instruction 

manual of the glue unit manufacturer for further information. Glueing is carried out by the hot melt unit. 

The glue temperature depends on the glue type used. 

Please note that the glue gun maintains its working temperature and is very hot.

5.4 Start/stop/emergency stop 

■ The main swith on the machine (7) must be switched to position 1 (ON). 

■ Compressed air must be connected and the compressed air cock must be open (9 and 10). 

■ The main switch on the glue tank must be switched to ON position. Check that there is glue in the 

tank. 

■ Check that all necessary carton size settings have been made (see the section “Setting of 

formats”). 

■ Close the doors in the guarding and check that the emergency stop switch (5) is pulled out. 

■ Push the AIR ON button (3). Air is connected to the machine and the white pushbutton with light 

(3) lights constantly. If this is not the case see the chapter regarding alarms. 

■ Push start (1). The machine now automatically starts a top sealing sequence. The green 

pushbutton with light lights constantly. If this is not the case see the chapter on handling of 

alarms. 

IMPORTANT: The glue tank indicator lamp must light green otherwise it is not possible to start the carton 

sealer. If the indicator lamp switches off when the machine is in operation the machine stops and it 

cannot be restarted until the indicator lamp lights. 

Stop 

Push the black button stop/reset (2) briefly to stop the machine when the top sealing sequence has 

ended. 

Reset 

Push the black stop/reset button (2) for 5 seconds to reset the machine until the green start button (1) 

flashes 3 times. This function is used when an alarm has occurred (see alarm instructions). All functions 

are reset which means that the machine returns to its initial position when air has been supplied to the 

machine or when air is supplied to the machine again. 

Emergency stop switch 

If the emergency stop switch (5) is activated the machine stops and is vented immediately. This also 

takes place if a door is opened. 

Queue control photocell S10 

When the photocell for queue control S10 (see wire diagrams) is activated the top sealing sequence is 

completed and the machine waits with the carton in the compression arrangement. When the photocell 

is free the carton is led out of compression arrangement and a new carton is led into the compression 

arrangement for sealing. 


Programme operation without cartons 

The machine is preprogrammed to operate without glueing for demonstration purposes. It is not required 

that the glue tank is connected and it is also not required that the movement speeds are adjusted. The 

machine must be stopped. 

■ Push the start button (1) and the stop button (2) for 3 seconds until the white AIR ON button (3) 

flashes 3 times. 

■ Now release the start button (1) and then push start again and the machine carries out the entire 

sequence over and over again until the stop button is activated. 


9

■ Push stop/reset (2) to return to normal operation.
