Claims
- 1. Apparatus for the application of a nonadhesive insulating strip to the winding of an electrical coil, in particular as intermediate, cover and/or shielding insulation, comprising:
- means for drawing a piece of a single sided adhesive tape from a first supply roll and applying said first piece to a first contact surface of a first pressure head;
- means for moving said first pressure head from a rest position into a working position, in which it adhesively bonds the adhesive tape to the winding of a coil;
- means for drawing a nonadhesive insulating strip from at least one second supply roll and bringing the nonadhesive insulating strip to a support surface of a second pressure head;
- means or subsequently displacing said second pressure head from its rest position into a first working position, in which it bonds the nonadhesive insulating strip to the adhesive tape;
- means for winding the adhesive tape together with the insulating strip onto the coil;
- means for cutting said nonadhesive insulating tape when said means for displacing said second pressure head subsequently pivots the second pressure head into a second working position, after which a residual of the nonadhesive insulating strip is wound together with the adhesive tape onto the coil; and,
- means for cutting the adhesive tape so that said means for winding winds a projecting end of the adhesive tape onto the coil.
- 2. Apparatus according to claim 1, wherein the means for drawing adhesive tape includes a tension relief device and means for holding said adhesive tape by suction on the first contact surface.
- 3. Apparatus according to claim 1, wherein said means for cutting the adhesive tape includes a blade located in the first pressure head and the means for cutting the nonadhesive insulating strip includes a blade located in the second pressure head.
- 4. Apparatus according to claim 3, wherein the second pressure head is pivoted for the cutting of the nonadhesive insulating strip in a manner such that a sliding surface of the second pressure head moves to a position of the support surface.
- 5. Apparatus according to claim 1, further comprising a plurality of pressure heads, each of which bonds an associated nonadhesive insulating strip to the adhesive tape in a mutually offset manner.
- 6. Apparatus according to claim 5, wherein plastic, metal or paper strips are used to form the nonadhesive insulating strip.
- 7. An apparatus for the application of a nonadhesive insulating tape to the winding of an electric coil comprising:
- a first pressure head means displaceable between a rest position and a working position, said pressure head being horizontally moveable so as to draw an adhesive tape from a supply roll, said adhesive tape being guided over a stress relieving device and held by suction on a support surface of the first pressure head, said pressure head further comprising a blade to cut the adhesive tape;
- at least one additional pressure head provided above the first pressure head and facing the latter, said additional pressure head comprising a support surface to hold a nonadhesive insulating tape drawn directly from at least one supply roll to the additional pressure head and a blade to cut the insulating tape.
- 8. Apparatus according to claim 7, wherein the additional pressure head is pivotally mounted, so that in a cutting position, a sliding surface is pivoted into a position previously occupied by the support surface.
