Abstract

DC60 Method of producing multilayer articles created as objects that are symmetrical around an axis which consists of at least a base of diameter D connected to the side walls. with an average thickness T and with a height H, which the above method consists of feeding the feed with multiple layers that are co-extruded into the cavities of the model, and then extruding the feeder in order to create an object. in which the feeder is formed as an axially symmetrical object around an axis of symmetry where the feeder consists of several radial overlapping layers. which at least one layer will be a layer that serves a thin where the outer diameter of the feeder is approximately equal to D, where the direction of compression is parallel to the axis of symmetry of Such a feeder , and where compression is performed on one surface of the feeder . The method is characterized by the fact that the feeder is compressed on one part of the such surface only Methods of producing multilayer articles created as objects that are symmetrical around an axis which such articles consist of at least a diameter D connected to the side wall with an average thickness T and with a height H, such a method consists of feeding with multiple layers that are co-extruded into the cavities of the model, and then extruding the feeder in order to create an object. in which the feeder is formed as an axially symmetrical object around an axis of symmetry where the feeder consists of several radial overlapping layers. which at least one layer will be a layer that serves a thin where the outer diameter of the feeder is equal to the quantity with D which the direction of compression is parallel to the axis of symmetry of Such a feeder , and where compression is performed on one surface of the feeder . The method is characterized by the fact that the feeder is compressed on one part of the such surface only

Claims (9)
