Abstract
A guide for a stack of disk-shaped elements, in particular for sheet-metal covers of cans, is provided which is formed of at least one longitudinally elongated profile element with a hollow cylindrical guide surface extending along the entire length of the profile element. Radially outside this guide surface is a guide passage for a flexible drive element which is seen in section cuts the section of the guide surface so as to form a gap such that the flexible drive element engages with the set-in sheet metal covers in frictional contact.
Claims8
A transport system for a stack of like disks, the system comprising:
- an elongated guide formed with
- a generally semicircular groove having a radius of curvature generally corresponding to that of the disks, and
- a substantially circular-section passage having a predetermined passage diameter and extending parallel to and opening partially at a fulllength slot into the groove, the slot having a predetermined transverse width substantially smaller than the passage diameter;
- and
- a substantially circular-section elongated guide strand in and generally filling the passage and projecting therefrom through the slot into the groove, the guide strand having a diameter greater than the transverse width of the slot, the strand being longitudinally displaceable in the passage and engaging the stack of disks standing in the groove to displace the disks along the guide.
