Abstract

Dispositivo pivotante perfeccionado en rodillos opresores de magnetófonos, caracterizado porque al citado rodillo presenta una cavidad axial dotada de un diámetro sensiblemente mayor que el diámetro del citado pivote de soporte, a excepción de un área de dimensión axial reducida, donde la cavidad y el citado pivote están normalmente en ligero contacto con posibilidad de rotación del uno respecto al otro; y porque el citado dispositivo comporta medios de tope que permitan al citado rodillo desplazarse con un movimiento angular, pero limitando los desplazamientos axiales del mismo con respecto al citado pivote, estando las diferentes partes dispuestas de manera que el citado rodillo pueda moverse angularmente con respecto al citado pivote realizando una rotación alrededor de un eje de giro paralelo al eje de rotación del citado capstan.
