ABSTRACT:
A method for the manufacture of a hose package by folding a hose of flexible material, where the hose package consists of folds adjoining one another and forming wall elements connected to one another. The elements are situated outside one another in relation to a central axis of the hose package. The device for carrying out the method has a fixing element and upper and lower folding plates in the shape of polygons. Through a controlled sequence of movements, the fixing element and folding plates form the folds situated outside one another, and thereby the hose package. The folding plates are placed adjacent to one another and in end regions form corners of the polygon. In the respective corner regions the plates are spaced from one another to form an opening or gap through which a pressing member can travel to contact the folds of the hose package and smooth out any wrinkles.
