Abstract:
Here is described an impregnation plant (10) for internally hollow cylindrical components (100) (stators) of electric motors. The plant (10) comprises a plurality of working stations arranged linearly and sequentially one after another, managed and controlled by central processing unit. The plant (10) also comprises a plurality of motor-driven means (18) configured to impart both a rotatory motion, in both directions of rotation, and a tilting motion, in both directions with respect to a predefined plane, to each component (100) mounted onto a respective support device (12) when such support device (12) is inserted into the working stations of the plant (10). Each support device (12) is provided with a spring collet (14), which is in turn provided with blocks clamping the component (100) onto the inner diameter of its respective cylindrical body (110). Each spring collet (14) entirely crosses the cylindrical body (110) of the component (100), so as to rest on both of its respective circumferential ends. An impregnation method (10) is also here described for components (100) of electric motors which uses said impregnation plant (10), wherein the component (100) is rotatable in both directions about a predefined axis of the support device (12), as well as tiltable with respect to a predefined plane of such support device (12).
Abstract:
A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.
Abstract:
A process for applying a coating material onto a substrate as a non-uniform patterned layer of coating material, the method including providing a first distribution manifold having a cavity and a first multiplicity of dispensing outlets in fluid communication with the cavity, providing a second distribution manifold having a cavity and a second multiplicity of dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction, dispensing a first coating material from the first dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction, and dispensing a second coating material from the second dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction. Useful non-uniformly patterned coated articles can be prepared using the process.
Abstract:
A fluid application device for applying fluid to a strand of material, a slot die applicator and a guide form for the fluid application device are provided. The fluid application device includes an applicator head and a slot die applicator secured to the applicator head configured to discharge the fluid onto the strand of material. The slot die applicator includes the guide form. The guide form includes a guide slot configured to receive the strand of material. The guide slot includes a strand inlet, a strand outlet and a positioning section between the strand inlet and strand outlet. A transverse dimension of the positioning section decreases along a direction from the strand inlet to the strand outlet.
Abstract:
A fluid application device (10), a nozzle assembly (22) and a method of applying a fluid onto a strand of material (12) provided. The fluid application device includes an applicator head (16) and a nozzle assembly. The nozzle assembly includes a guide slot (34) for receiving a strand of material. The nozzle assembly further includes an orifice (28), spaced from the guide slot, configured to discharge a first fluid to onto the strand, and at least one outlet (29), adjacent to the orifice, for discharging a second fluid to act on the first fluid. The method includes positioning the strand at the closed end of the guide slot so that the strand is spaced a predetermined distance from the orifice, feeding the strand through the guide slot at a predetermined speed, applying the first fluid onto the strand from the orifice and discharging the second fluid from the at least one outlet.
Abstract:
An adhesive application device for applying an adhesive to a material which is moved along a transport direction x, comprising a nozzle unit with a number of nozzles for applying the adhesive to the material, is to be capable in a very simple way of processing adhesive patterns of different size particularly flexibly and efficiently. To this end, the nozzle unit is arranged such that it can be displaced along a first guiding axis transversely with respect to the transport direction x.
