The ProCo masking machine has been designed to be very flexible with the product sizes that can be accommodated and to be easy to size/format change.
The ProCo Masking Machine enables cigarettes to be loaded via a tray system into a feed hopper and then transported through the unit via a series of rotating drums on which the cigarettes are held and released by using suction provided by an integral fan unit.
Masking paper which is similar to cigarette tipping paper is fed from a bobbin, cut and ‘rolled’ onto the cigarettes in a position which enables the cigarette identification marks to be ‘masked’. PVA adhesive is uitilised to adhere the masking paper to the cigarettes.
An online ink printer is then used to print the masked cigarettes with a new identification.
All the drums throughout the entire machine are designed and fitted with ‘quick release’ mechanisms to enable fast changes. Additionally where possible the drums are machined to enable more than one diameter to be accepted for quick changes which also reduces the number of change parts.
The base structure of the machine is a fabricated steel frame which is machined as required and upon which is mounted a 20mm thick plough ground steel tooling plate providing strength and rigidity. The main machine drive is through a gear train via an inverter controlled main motor and timing belt.
A unique design has been utilised for the cork drum which enables adjustment for different suction port positions. The machine design includes the tray station and rod feed system being mounted on a sub plate which is easily and accurately adjusted for position. Furthermore the same design criteria has been applied for the cork bobbin and cork drum assembly which are mounted on a sub plate for easy and accurate adjustment. The ‘Masking Machine’ is easily maneuverable as it is fitted with ‘castors’ and adjustable feet for use when it is in position.
Based on proven technology. Modular design and construction. Drums where possible are machined to enable more than one diameter to be accepted for quick changes. A unique design has been utilised for the cork drum which enables adjustment for different suction port positions.
