Bar end blocks are attached to the ends of a heat sealing bar. Their function is as follows:
- To fasten the heat sealing band
- To connect the high-current and measurement cables
- To allow the hot heat sealing band to expand due to spring force
- To prevent the heat sealing band from bending or warping
Screwed electrical connections are essential here. Plug-in connections are not allowed because even minimal contact resistances will distort the temperature measurement. Since these connections are generally at one end, there is always a left and right-hand bar end block. Bar end blocks have different technical characteristics depending on the dimensions of the heat sealing band or the end pieces.
