Hola a todos, no estoy encontrando este término "stenter over" para esta patente.

Sequential stretching can be used, in which heated rollers effect stretching of the film in the machine direction and a stenter oven is thereafter used to effect stretching in the transverse direction. Alternatively, simultaneous stretching, for example, using the so-called bubble process, or simultaneous draw stenter stretching may be used.

Gracias por cualquier ayuda!
