Abstract:
Coating apparatus including a spray to provide a coating, a controller to control the spray to vary a spraying width of the spray, and a first roller to receive the coating and to smear the coating on a substrate.
Abstract:
There is provided a coating die for applying an insulation varnish around a wire conductor, comprising: a die body; and a die hole formed through the die body, the die hole including: an entry portion having an opening size monotonically decreasing along a conductor insertion direction; and a coating portion comprising a sub-portion having a constant opening size, in which: on an inner surface of the coating portion are provided at least four protrusions equally spaced in a circumferential direction of the inner surface, the protrusions projecting toward a center axis of the die hole; and each of the protrusions includes a portion with a height gradually increasing along the conductor insertion direction from a boundary between the entry portion and the coating portion. There can be formed an enameled wire having a thin and uniform insulation coating by using the invented coating die.
Abstract:
A solid coating die for applying an insulation varnish around a flat wire conductor includes a die body and a die hole formed through the die body, the conductor to be inserted into the die hole. The die hole includes: an entry portion having a cross section monotonically decreasing along a conductor insertion direction; and a coating portion including at least a sub-portion having a constant cross section. The cross section of the coating portion is a rectangle having four straight sides and four rounded corners. Each inner surface of the straight side of the coating portion has an inwardly projecting protrusion, a top contour of each protrusion being a circular arc, an elongated circular arc, an elliptical arc or a combination of these arcs, the maximum curvature of the top contour of each protrusion being larger than the maximum curvature of inner surface of the rounded corners.

Abstract:
The device for coating an element with a swab impregnated with a coating composition includes a mobile carriage bearing the swab wherein the carriage is movable along a guiding path, a member for pushing the swab towards the element to be coated so that a quality of the composition released from the swab coats the element, and a member for varying the release of the composition so that the coating is substantially uniform.
Abstract:
A method of applying liquid material, for example, liquid resin, to elongated material, for example glass fiber strands, includes maintaining a supply of the liquid resin in a container and using a partially immersed roller for transferring some of it from the container to a stationary, preferably flat, surface which is positioned out of direct contact with the resin supply. The glass fiber strands are moved over the stationary surface and through the liquid resin thereon. An assembly for accomplishing this is also disclosed herein.

Abstract:
According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.
Abstract:
A method of manufacturing a pressure sensitive adhesive waxed cloth tape comprising a fabric substrate having an adhesive layer infused on one surface and a wax layer infused on an opposing second surface, the wax layer including a tackifier resin. The pressure sensitive adhesive waxed cloth tape may be used to prevent buildup of snow and ice on a hockey stick blade during exposure to moisture, cold temperatures, snow, ice, and other harsh conditions. The tape will easily adhere to itself when in a rolled position prior to use or when overlapped on the stick blade while in use.
