Abstract
A method and an apparatus for packaging paper rolls (2), wherein a wrapper sheet (1) of such a size as to exceed the axial length of the roll is wrapped around the roll and the width of the wrapper sheet is reduced to a size corresponding to the length of the roll by removing the part (5, 6) of the wrapper sheet which extends over the ends of the roll. The header sheet (14, 15) which is bigger than the end surface of the roll, is placed on the ends of the roll and reduced to a size corresponding to the diameter of the roll or smaller by removing at least the part of the header sheet extending over the end surface. Thereafter the header (14, 15) and the wrapper (25) are secured to each other so that a tight joint is formed.
Claims6
A method for packaging a paper roll or the like in which a wrapping material is wrapped around the roll and headers are secured to the ends of the roll, which consists of the steps of
- (a) wrapping a wrapper sheet (1) of width greater than the axial length of the roll (2) around the roll,
- (b) securing the wrapper sheet to the roll,
- (c) removing the portions (5,6) of the wrapper sheet which extend over the ends of the roll, whereby the width of the wrapper sheet is reduced to the size of the length of the roll,
- (d) placing header sheets (14,15) of size greater than the end surface of the roll against the ends of the roll,
- (e) removing at least the edge portion of the header sheets extendng over the end surface and reducing the header sheets to obtain headers of the size of the roll diameter or smaller, while the roll is rotated,
- (f) securing the headers to the wrapper so that a tight joint is formed.
An apparatus for wrapping a paper roll or the like which comprises means for wrapping a wrapper sheet around the roll, means for placing a header sheet against each of the roll ends, means for rotating the roll, cutting means (7,18) provided with cutting tools (28,30) adapted to be placed against the roll for removing the edges of the wrapper sheet (1) and the header sheets (14,15) extending beyond the ends of the roll, means (21) for feeding a jointing material (20) and means for securing the jointing material to the edges of the wrapper and to said header sheets.
