Abstract:
More than 100 years ago the first tube winding
machine was designed. However, convolute
tube winding was very slow and could produce
one tube only at a time. Hence a process had to
be found to run this intermittent procedure continuously,
for which a plastic extruder-is an excellent
example. A further advantage of such a
method is that the tube can be supplied of practically
endless lengths instead of one set length.
The tube is cut off according to need.
