be possible to change the final part by lifting it from the special handles and by replacing it according to cleaning needs or the necessity to change the strands number or size to be

tips.<\/p>\n<p>Therefore, only four screws will require handling and there will be neither hot parts nor a certain weight to support.<\/p>\n<p>Another significant aspect is the side heating of the die. In many cases \u2013and above all with the new high-productivity machines \u2013 the supply chain is very wide and implies the possibility to reach different temperatures according to the various areas, which \u2013 in turn \u2013 generate irregular flows with consequent strands of different diameters.
