dispositivo para dispensação de materiais em tiras

dispositivo para dispensação de materiais em tiras. a presente invenção refere-se a um aparelho para dispensação de materiais em tiras sobreum ou mais substratos em movimento que inclui uma estrutura que se estende transversalmente à trajetória do substrato que suporta braços-guia. cada braço-guia inclui polias para dispensar materiais em tiras e pode ser movido ao longo da estrutura por um sistema de acionamento por fricção, que inclui manivelas, polias e cabos. cada braço-guia pode ser mantido em posição por um sistema de frenagem por fricção, que inclui elementos que são pressionados contra os componentes do sistema de acionamento para evitar por fricção o movimento. um sistema de retroinformação de posição mede e mostra a localização dos braços-guia. um sistema de rastreamento e ajuste de substrato rastreia a posição do substrato à medida que o mesmo se move de um lado ao outro de uma trajetória normal e ajusta automaticamente a posição da estrutura ao longo de um trilho-guia para manter os braços-guia em uma posição desejada em relação ao substrato.

Strip material dispensing device

Metodo y articulo de cinta libre de husillo.

Un artículo de trama adhesiva que incluye una trama adhesiva que define una primera superficie, una segunda superficie, un primer extremo, un segundo extremo, una longitud entre estos, y una capa adhesiva que define una primera superficie adhesiva. La trama adhesiva se pliega sobre sí misma a lo largo de la longitud de tal manera que una primera porción de la primera superficie adhesiva esté en una relación de orientación con una segunda porción de la primera superficie adhesiva.

Material application system

A system for applying a material to a substrate comprising: a feed section that comprises a feed roll and configured for advancing a material along a predetermined path; a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate; a knife element located between the feed section and the material applicator roll; and a non-vacuum anvil roll positioned near the knife element, wherein the knife element and the non-vacuum anvil roll are positioned along the path of the material and engage the material to cut the material into the cut length of material for applying to the substrate, and wherein the material contacts the peripheral surface of the non-vacuum anvil roll only at a cut engagement point.
