Abstract
An electromagnetic weaving machine for the strings of tennis rackets achieves a high prodn. speed and better cordage. The distance between the vertical strings has no effect on the rate of prodn. and it is possible to m.f.r. all sizes of tennis rackets. The machine is made with two electromagnets switched by an alternating switch to control the current from one electromagnet to the other. The weaving is produced by linear displacements of the two electromagnets. The frequency of the switch and the speed of the motor are regulated.
Description
"het electromagnetisch weven van de horizontale snaren van tennisraketten."
WERKING:
Het principe van het electromagnetisme
<EMI ID=1.1>
wisselschakelaar,die de stroom stuurt van de electromagneet A naar de electromagneet B. Door een lineaire verplaatsing van
de beide electromagneten ontstaat er een weving.
Er zijn twee regelaars gelijk aan de frequentie van de wisselschakelaar en de toerentallen van de motor die de electromagneten A en B aandrijft. Daardoor ontstaat de mogelijkheid dat men hetzij vlugger,hetzij trager kan corderen, en dat de tussensporen tussen de vertikale en horizontale snaren kunnen bepaald worden door de frequentie,met als gevolg dat de afstand tussen de vertikale snaren geen rol speelt.
Om het systeem perfect te laten functioneren wordt aan de snaar een nylondraadje bevestigd met een klein naaldje met als gevolg dat de snaren helemaal niet gesch onden worden en men een betere cordage verkrijgt.
<EMI ID=2.1>
1./ Vluggere weving van tennisraketten door middel van elkaar
aantrekkende electromagneten in plaats van manuele weving.
2./ De snaren worden niet meer geschonden.
3./ Betere cordage.
<EMI ID=3.1>
5./ De afstand tussen de vertikale snaren speelt voor de
werking ge en rol zodat de toepassing van het procédé mogelijk is voor elke soort ( lees.: size ) van tennisraketten.
"electromagnetic weaving of the horizontal strings of tennis rockets."
OPERATION:
The principle of electromagnetism
<EMI ID = 1.1>
changeover switch, which directs the current from the electromagnet A to the electromagnet B. By a linear displacement of
the two electromagnets create a weave.
There are two controllers equal to the frequency of the changeover switch and the speeds of the motor driving the electromagnets A and B. This creates the possibility that one can corrode faster or slower, and that the intermediate tracks between the vertical and horizontal strings can be determined by the frequency, with the result that the distance between the vertical strings does not matter.
For the system to function perfectly, a nylon thread is attached to the string with a small needle, as a result of which the strings are not damaged at all and better cordage is obtained.
<EMI ID = 2.1>
1. / Faster weaving of tennis rockets through each other
attractive electromagnets instead of manual weaving.
2. / The strings are no longer violated.
3. / Better cordage.
<EMI ID = 3.1>
5. / The distance between the vertical strings plays for the
operation and roll so that the application of the process is possible for any type (read .: size) of tennis rockets.
