Lid Forming Machines
Overview
The lid forming machine processes round rings and discs of cardboard to lids for round containers.
The spirally wound rings are fed from the ring dividing machine via a conveyor belt to the lid forming machine.
The pre-punched cardboard discs are separated from a magazine.
Process
Working Steps
| cycle | RING | disc |
|---|---|---|
| 1 | separating and transferring from the infeed conveyor belt to the star wheel at the infeed for rings | - |
| 2 | oling the top rim (to facilitate the crimping process in cycles 6 and 7) | separating from stack by vacuum suction |
| 3 | transferring from the star wheel at the infeed for rings to the main plate | bending up the rim of the disc |
| 4 | inserting the disc into the ring | |
| 5 | applying glue to the rim of the disc | |
| 6 | pre-crimping (bending the top rim of the ring from vertical to horizontal) | |
| 7 | final crimping (bending the top rim of the ring from horizontal to vertical) | |
| 8 | transferring from the main plate at the discharge point for rings | |
| 9 | grooving (The groove running around the ring on the outside provides for a ridge running around the ring on the inside. The ridge enables the lid to snaü in later on when it is put onto a container) | |
| 10 | transferring the finished lid from the plate at the exit for lids to an exit conveyor belt | |
