Abstract

método para desenrolar materiais de trama (n1, n2) de duas bobinas principais correspondentes (1, 2), e desbobinador configurado para desenrolar materiais de trama (n1, n2) das respectivas bobinas principais (1, 2). método para desenrolar materiais de trama de duas bobinas principais (1, 2), em que uma primeira bobina principal (1) em uma fase de esgotamento é substituída por uma segunda bobina principal (2), em que durante a referida substituição um primeiro e um segundo material de trama (n1, n2) são desenrolados de ambas as bobinas principais, em que antes da conclusão da referida substituição o primeiro material de trama (n1) é unido ao segundo material de trama (n2) e depois é cortado, em que a junção dos referidos materiais de trama (n1, n2) é precedida pela inserção do segundo material de trama em uma área onde os dois materiais de trama são unidos e durante a etapa de inserção do segundo material de trama na referida área de junção o segundo material de trama é guiado em uma superfície guia (41, 44) que o guia em direção à área de junção. na referida etapa de inserção, o segundo material de trama adere pneumaticamente à superfície guia.method for unwinding weft materials (n1, n2) from two corresponding main coils (1, 2), and unwinder configured to unwind weft materials (n1, n2) from respective main coils (1, 2). method for unwinding weft materials from two main coils (1, 2), wherein a first main coil (1) in an exhaustion phase is replaced by a second main coil (2), wherein during said replacement a first and a second weft material (n1, n2) are unwound from both main bobbins, wherein prior to the completion of said replacement the first weft material (n1) is joined to the second weft material (n2) and then is cut, in that the joining of said web materials (n1, n2) is preceded by the insertion of the second web material into an area where the two web materials are joined and during the step of inserting the second web material into said joining area the second web material is guided on a guide surface (41, 44) which guides it towards the joining area. in said insertion step, the second web material pneumatically adheres to the guide surface.
