Rotary packaging machine to stack profiled sections.

摘要

Method to package sections either in normal layers or in alternate right-side-up/overturned layers, the layers being fed from determined layers, whereby two already butted layers, one having a number N of sections and the other having a number N-1 of sections, or viceversa, reach the packaging machine by moving axially at one and the same time, the layers having been distanced apart laterally beforehand by a required value linked to the features of the packaging machine, the first layer (30) of "N" sections arriving and being positioned directly on a package (29) being formed, whereas the second layer (31) of "N-1" sections arrives between a plurality of pairs of clamping arms (24) able to rotate about an axis located in a central position between the two layers (30-31), the pairs of clamping arms (24) positioning the second layer (31) on the package (29) being formed. Rotary packaging machine able to package sections either in normal layers or in alternate right-side-up/overturned layers according to the above method, the packaging machine being fed by determined layers of the sections and comprising a plurality of pairs of clamping arms (24) able to rotate about an axis which is located along the length of the packaging machine and which is parallel to the package (29) being formed, the clamping arms (24) lying on a plane passing through and radial to that axis, the axis of rotation lying between the two planes of axial arrival of the sections, the arms (24) being secured to rotary means (21).
