Abstract: The wrapping includes two front end discoidal lids with cylindrical perimetral covers, suitable to surround the coil; each of the two lids is made up of at least two parts (21, 23; 25, 27) defined by radial planes, as two half-covers, which are assembled one after the other, each resting on the top part of the coil B, and making the coil itself resting on rollers 35 rotate; the two lids are made so that they overlap when they are assembled on the coil axially opposite to one another.

Abstract: The machine, which operates in association with a paper feeder and with a system of rolls for revolving the coil, includes the following equipment: guide rolls resting on the cylindrical surface on the coil; primary folding devices, including screw rollers, for pleating the open ends of the paper against the circular sides of the coil; and secondary folding devices, including additional screw rollers, for bending back the edges of the paper into the hollow core of the coil.

Abstract: A protective wrapper made of sheet metal for individual cylindrical ribbon coils of coiled metal sheeting to protect the coils individually from damage and from atmospheric corrosive agents. The wrapper is constructed from two discoidal end caps having a band defining a sleeve open at one end and an annular, radially inwardly projecting flange at the other end. The caps are disposed at opposite ends of the coil with the band or sleeve thereof extending toward each other. Each sleeve has an axial extent so that they overlap along marginal edges at the open ends over the coil. Each flange has pleats or corrugations extending radially increasing in depth toward the center of the coil. Each end cap flange has a center opening which will align coaxially with the center of the coil. A tubular insert for each end is inserted into the center of the coil and each insert has a radial flange extending outwardly to overlap the corresponding end cap flange.
