Abstract

"MéTODO PARA MUDAR A FORMA DE UMA LATA E LATA MOLDADA DESSA MANEIRA". A invenção refere-se a um método para mudar a forma de uma lata (2), que tem uma parede de lata, tal como uma lata de estampagem profunda ou uma lata com parede de ferro, a lata sendo posicionada na ou em torno de uma matriz (1), matriz que é dotada de uma superfície com, por exemplo, um relevo, sulcos ou seções espessadas, após o que a parede da lata é comprimida na forma da matriz por meio de pelo menos um jato de um meio de alta pressão, que é movido ao longo da parede da lata. De acordo com a invenção, uma camada de sustentação (3), que suporta a parede de lata durante a deformação da parede de lata, é disposta entre a parede de lata e a matriz. A invenção também refere-se a uma lata moldada usando o método."METHOD TO CHANGE THE SHAPE OF A CAN AND MOLDED CAN IN THIS WAY". The invention relates to a method for changing the shape of a can (2), which has a can wall, such as a deep-drawn can or an iron-walled can, the can being positioned in or around a matrix (1), matrix that is provided with a surface with, for example, a relief, grooves or thickened sections, after which the wall of the can is compressed in the shape of the matrix by means of at least a jet of a high pressure, which is moved along the can wall. According to the invention, a support layer (3), which supports the can wall during deformation of the can wall, is disposed between the can wall and the die. The invention also relates to a can molded using the method.
