Coil production<br />
<strong>Von</strong> <strong>Roll</strong> is heavily involved in every aspect of high-voltage technology, including<br />
process equipment. For high-voltage motors <strong>Von</strong> <strong>Roll</strong> M Tec has developed a line<br />
of coil-producing machines that use flat-coil technology. This line of equipment<br />
includes the following units:<br />
• Wire dispensing and preparation<br />
• Loop winding<br />
• Taping<br />
• Coil forming<br />

Stack consolidation<br />
Depending on the system, stack consolidation may be included.<br />
Employing Samicafilm with a hot-melt adhesive or glass lapped wires in B-stage<br />
enables rapid consolidation of conductor stacks without the need for additional<br />
consolidation products.<br />
When using Samicafilm without hot-melt adhesive or non-B-stage wires, traditional<br />
hot-press consolidation is preferred. This system can be achieved by overlapping<br />
the stack with Thermopreg 251.78.<br />
