Abstract
A coil support and a winding arranged thereon, especially one including a fiber-optic waveguide, whose turns are mutually fixed by a binding agent. The binding agent drys while a volatile solvent diffuses off. The coil support is permeable to solvent and is designed such that it has essentially the same coefficient of thermal expansion as the winding. This achieves the uniform, thorough drying of the binding agent over the entire winding and reduces the risk of damage to the fiber-optic waveguide during the transportation and the unwinding of the winding in a coil form.
Claims17
A coil form, comprising:
- a coil support having a coil support wall with a winding receiving area;
- a winding arranged on said coil support wall at said winding receiving area, said winding having turns mutually fixed by a binding agent containing a volatile solvent, said binding agent drying while said volatile solvent diffuses off, said coil support having substantially, the same coefficient of thermal expansion (.alpha.) as said winding,
- said coil support winding receiving area being solvent-permeable, said winding receiving area being covered by said winding to define a solvent diffusion region whereby said binding agent is dried while said solvent diffuses through said coil support wall.
A process for forming a coil form, comprising the steps of:
- providing a coil support;
- disposing a winding on said coil support, said coil support being a solvent-permeable coil support having substantially the same coefficient of thermal expansion (.alpha.) as said winding;
- fixing said turns of said winding with a binding agent including
- applying said binding agent with a volatile solvent;
- and
- drying said binding agent while said volatile solvent diffuses off.
