introduCtion
the Blizzard heating press is an all-in-one solution for splicing thermoplastic conveyor belts (e.g. pVC, polyurethane).
no external control box, air pump, or water cooling tank are required.
the heating presses are provided with electric heating and built in air cooling. the splice process runs fully automated.
if the belt is relatively thick a problem might occur where the outside of the belt is at the splicing temperature too long,
waiting for the inside to reach the required temperature. melted material might flow away or discolor and fabrics might
shrink. to avoid this problem, the preheat option can be used. this option heats the belt up (outside and inside) to a tem-
perature just below the melting temperature. after the preheat stage, the inside splice temperature can be reached much
quicker, minimizing the risk for unwanted flow of material, discoloring or fabric shrinkage.
Basic process
• Splice pressure is applied by an internal compressor,
max. 2.5 bar (36.3 psi). siegling Blizzard hp 160/1500 air:
max 2.0 bar (29 psi).
• Heats up to a splice temperature of max. 200 °C (392 °F)
• Keeps it at the splice temperature (adjustable dwell time)
• Cools down to the cooling temperature
(safe temperature to take the belt out)
• For thicker belts a preheat temperature and preheat
dwell time can be applied
• The bottom heating can be set lower or higher than
the top heating
