Abstract (en)
[origin: EP0515704A1] A column is indented around the outside by moving the said column (1) initially between two rollers (5, 5-5', 5') of in each case a pair of indenting rollers arranged one behind the other and is indented on two opposite sides of the column. Subsequently, the pairs of indenting rollers (5, 5-5', 5') are moved transversely with respect to the said first direction of movement of the column towards each other, the pairs of rollers clamping the column between them and indenting from the edges on the two other opposite sides of the column, whereupon the column is moved through between the two indenting rollers of each pair of indenting rollers (5, 5'-5,5') in a second direction of movement, and thus an indenting around the outside is produced. <IMAGE>
