Title (EN) METHOD FOR PRODUCING AND APPLYING HOT-MELT ADHESIVES
(FR) PROCÉDÉ DE PRODUCTION ET D’APPLICATION DE COLLES THERMOFUSIBLES
(PT) PROCESSO DE PRODUÇÃO E APLICAÇÃO DE COLAS TERMOFUSÍVEIS
Abstract:
(EN) The present invention relates to a method for producing and applying hot-melt adhesives, comprising the following steps: adding at least one polymer and one adhesion agent to a homogenizer/melter; mixing and heating the at least one polymer and one adhesion agent to a temperature above the melting point of the mixture to obtain a melted glue; transferring the melted glue to a melted-glue application mechanism; and applying the melted glue. The present invention also relates to the use of the method for producing and applying the melted glue in systems used for packaging, labelling, producing nappies, self-adhesive labels, laminating and the like.
(FR) La présente invention concerne un procédé de production et d'application de colles thermofusibles, dont les étapes consistent : à additionner au moins un polymère et un agent d’adhésion à une unité d’homogénéisation/fusion ; à mélanger et chauffer ledit au moins un polymère et ledit au moins un agent d'adhésion jusqu'à une température supérieure à la température de fusion du mélange, de manière à obtenir une colle fondue ; à transférer la colle fondue vers un mécanisme d'application de colle fondue ; et à appliquer la colle fondue. La présente invention concerne également le procédé de production et d'application de la colle fondue sur des systèmes de conditionnement, d'étiquetage, de production de couches, d'étiquettes autocollantes, de contrecollage, entre autres.
(PT) A presente invenção refere-se a um processo de produção e aplicação de colas termofusíveis que consiste nos passos de: adicionar, pelo menos, um polímero e um agente de adesividade a um homogeneizador/fundidor; misturar e aquecer os, pelo menos, um polímero e um agente de adesividade, até uma temperatura acima da temperatura de fusão da mistura, obtendo-se uma cola fundida; transferir a cola fundida para um mecanismo de aplicação da cola fundida; e aplicar a cola fundida. A presente invenção refere-se ainda à utilização do processo de produção e aplicação da cola fundida em sistemas de embalamento, rotulagem, produção de fraldas, etiquetas autoadesivas, laminagem, entre outros.
