Abstract:
An apparatus and method for shirring netting onto a netting tube. A second tube is placed over and coaxially to the netting tube and netting is stretched over the second tube. The two tubes are caused to move in a reciprocating manner through a plurality of spring-loaded fingers, which allow the netting to pass on the downstroke and hold the netting on the upstroke. As the two tubes move, the netting is pulled over the second tube and shirred onto the netting tube. An annular space formed by a tube ring placed between the netting tube and the second tube causes the netting to shir in multiple, neatly aligned layers.

Abstract:
La invención se refiere a la forma y medios utilizados para realizar una ordenación en multicapa de una red de forma tubular (6) previamente situada en un tubo de transferencia (3). Mediante un cargador dentado (5) se efectúa el deslizamiento de la red (6) por el exterior del tubo de transferencia (3), hasta el final de éste, el cual tiene una zona extrema ligeramente cónica (4) desde el cual la red (6') que es arrastrada por el cargador dentado (5), debido a la tensión elástica de aquella, cae sobre el tubo soporte (1), de manera que éste se va cargando con la red, para que se consiga una ordenación en capas concéntricas (6') sobre dicho tubo soporte (1), todo ello de manera tal que las capas exteriores de la red cargada (6'') tendrán un diámetro máximo igual al del tubo de transferencia (3), mientras que el diámetro interior de la red cargada (6''), que coincide con el diámetro exterior del tubo soporte (1), es inferior al diámetro máximo de la red cuando está tensionada.
Abstract:
The invention relates to a method for producing a shirred food casing covered by a tubular net and to a method for applying a net to the surface of a carrier casing. This method comprises steps wherein air or an inert gas is blown into the carrier casing, the carrier casing inflated/pressurised to become round is pulled in the direction of the net towards a pleating head attached to one end of the net, which is attached, at the open end thereof, to a clamp centralised with a shirring mandrel. Thus, the carrier casing is folded into the tubular net while pulling the net inside out over itself, whereafter the carrier casing is pulled through the pleating head to the shirring machine, where the pressure of air or an inert gas blown from inside of the shirring mandrel forces the areas of the carrier casing between the meshes of the net to form bulges. Finally, the net/carrier casing combination is shirred by the shirring machine.
Abstract:
La envoltura se materializa en un soporte cilíndrico, hueco y rígido (1), provisto de un sistema de sujeción (2) para su acoplamiento al tubo de embutición, sobre el que está dispuesto un tubo (3) convenientemente plisado, que a su vez queda recubierto por una hoja de separación (4) y finalmente por una red (5), tubular, igualmente comprimida o plisada, que conjuntamente con el tubo interior (3) se prolonga más allá del tubo soporte (1) y se estrangula también conjuntamente con éste último mediante un clip, grapa o nudo (7), de manera que durante la embutición se produce la extensión axial tanto del tubo plisado (3) como de la red (5) igualmente plisada, viéndose favorecida la extensión simultánea pero independiente de ambos elementos con la colaboración de la hoja de separación intermedia (4).
