Abstract: A sealed rectangular parallelepiped polypropylene conditioning package with fast tear-off opening for pasty products likely to melt into a semi-liquid state, in particular cheese, includes a first sheet (1) cut out along a suitable contour and having a rectangular shell-type shape for receiving the product and for providing a gripping corner (2) for opening the package, a cover sheet and two tear-off strips (5, 6). The gripping corner (2) has a triangular projection formed on one of the sides of the first sheet cut out into an octagonal shape and the tear-off strips (5, 6) form a pointed U shape whereof the tip is located in the triangular projection, thereby making it easy and simple to open.

Abstract: The conveyor comprises a conveyor belt (5), two main drums (R1,R4) around which the conveyor belt forms a main loop, two auxiliary drums (R2,R3) mounted between the main drums and around which the conveyor belt forms a secondary loop, and two auxiliary rolls (R5,R6) close together and forming a return for the upper strand of the conveyor belt towards each of the auxiliary drums. The main drum (R1) located at the end where objects begin to be conveyed is shifted as one back and forth parallel to the conveyor belt in such a way that as it shifts backward, the conveyor belt has a section (S1) with zero speed. The forward travel is such that an object placed on the zero-speed section catches up with the objects lying on that section of the belt that is traveling at constant speed.
