Design and function
The eyelets are held in the storage container of the feeding device [3/5.2.1].
This moves the eyelets out of the storage container in the correct position
and into the feed channel. The eyelets are buffered in the feed channel and
then fed to the eyeletting tool.
The gear motor drives the crank handle which, together with the rod, moves
the lever arm up and down.
The lever arm is equipped with a strap and a gear segment.
The strap transfers the force to the cylinder. At the other end of the cylinder
is the upper punch with catch pin which presses in and rivets the eyelet.
The riveting process creates a non-detachable, frictional, load-bearing
connection between the parts being joined (e.g. paper stack) by
reshaping the eyelet.
Reshaping is carried out by pressing the tool onto the eyelet.
The upper punch introduces the eyelet and cuts through the paper stack.
The lower punch reshapes the lower end of the eyelet (see image
below). The upper punch moves back and releases the eyelet
connection.
