    • Method for forming multiply paper or board product, where all the plies are formed by means of roll forming of the type where the fibre suspension jet is introduced in the twin-wire nip at such a speed that the outer wire of the tensioned wires (2; 10; 17) is deflected while maintaining a substantially constant tension during the deflection of the outer wire, by the fact that the outer wire is supported by a rotating support (5; 14; 19), at least one of which being resiliently or displaceably mounted to compensate for said deflection. The forming of each ply occurs over only one forming roll (4; 11; 18), wherein the wire winding angle (α) over the forming rolls is at least 110°, that the forming rolls are located alternatingly in two planes, that for the forming roll (rolls) in the upper plane the wires leave the roll in a lower quadrant (G, H) where the paper web follows the outer wire, and for the forming roll in the lower plane the wires leave the roll in an upper quadrant (E, F), where in this case the paper web also follows the outer wire.

    • The present invention relates to a package comprising a one-piece blank whereby the side walls have support tabs (12) which project from them at both ends and which are delimited from the edge sections by means of a first fold indication (13), and whereby the support tabs (12), in a storage state, are located in the same plane as the raised first edge sections (2,3), as a result of which the packages, with their edge sections diverging from the bottom section in this unfilled state, can be pressed down into each other for space-saving stacking of empty packages, and whereby the support tabs (12) are provided with locking portions (16) and, after the support tabs have been folded down to a support position in which each support tab (12) rests against an upper edge of the adjacent second edge section (4,5), said locking portions (16) are arranged to project completely outside said upper edge.
    • 本发明涉及一种包括单件式坯件的包装,其中侧壁具有支撑片(12),所述支撑片在两端从它们突出并且借助于第一折叠指示(13)与边缘部分界定,以及 由此在存储状态下,支撑突片(12)位于与凸起的第一边缘部分(2,3)相同的平面中,由此使得其边缘部分在此处与底部部分分开 (12)被设置有锁定部分(16),并且在支撑突片已经被折叠到支撑位置之后,所述支撑突片可以被压入彼此中以便节省空间堆叠空的包装, (12)靠在相邻的第二边缘部分(4,5)的上边缘上,所述锁定部分(16)布置成完全突出到所述上边缘之外。
