Blocking a stretch blow moulder and labeller brings many advantages. And that is the reason why we have further perfected the combination of both machines in one block. With a seamless drive concept, finely tuned transfer interfaces for every production program and precisely operating processes in stop situations, you can count on getting the very best out of your PET bottle production.

One operator for all machines

The block is designed as one unit in which all essential control and function elements are centrally combined. This way, just one operator can easily operate the entire Contiform Bloc BL on his own.

Trouble-free continuous operation

Full power with no breaks: The labelling module automatically detects bottle gaps and does not apply glue or labels in this case. Disruptions due to missing bottles and unnecessary glue and label consumption are therefore not an issue.

Cost-efficient customisation

A wide range of equipment options make it possible to adapt the block to special requirements and keep the costs as well as the commissioning time low at the same time.

Gentle treatment for PET containers

The active transfer grippers only touch the preforms and bottles in their neck area. This makes the contact area between the material and the machines as small as possible and minimises the risk of damage.

Energy savings

From the servo drives to the electromagnetic and compressed-air free stretching systems: The topic energy efficiency goes all the way through the block just like a red thread. Particularly ambitious savings targets can also be achieved with the air recycling system, which is part of the energy-saving package.

Energy efficiency

• Increased station performance during stretch blow moulding and labelling
• Reduced energy consumption thanks to the omission of transfer starwheels and redundant components
• Lowest possible heating energy requirement through energy optimisation of heating zone and heaters
• Energy-efficient separated vacuum during labelling

Media efficiency

• Efficient cooling of the entire block
• Air Wizard Triple compressed-air recovery system
• No compressed-air consumption during the filling process

Environmental compatibility

• Use of enviro-compliant lubricants
• Recoverable CIP media
