of the two narrow end walls 3 a is situated approximately underneath the free end of the cover plate 10 the short approximately 40 mm sliver end 4 a hangs downwardly from the upper edge of the can wall 3 a in the region of the free end of the cover plate 10 a pneumatic suction device 12 is arranged which is shown in more detail in fig5 upon turning on a suction stream e as shown in fig3 b the short band end 4 a is drawn upwardly against the cover plate 10 and is firmly held there by the force of the suction stream e thereafter the coiler can 3 is as shown in fig3 c further shifted in the direction of the arrow f whereby a lengthened band end 4 b is obtained subsequently the suction stream e is turned off so that the lengthened band end 4 b drops down from the suction device 12 and remains hanging on the end wall 3 a by gravity in fig4 the short sliver end 4 a whose terminal edge is shown in broken lines and the lengthened sliver end 4 b whose terminal edge is shown in solid lines are illustrated the short sliver end 4 a has a length a which extends from the upper edge of the can wall 3 a to the free edge of the short sliver end the lengthened sliver end 4 b has a length b of for example 125 mm extending from the upper edge of the wall 3 a to the free sliver edge shown in solid lines the lengthened free sliver end 4 b is situated in a generally rectangular u201c.
