The Roll handling solutions of Dotec meet the standards of ergonomics, working environment, safety and efficiency. With an unique integration of mechanical, electric, pneumatic features which minimises maintenance and maximises the efficiency of your production process.
Roll handling solutions by Dotec
Dotec handlers are operational worldwide, many in production facilities where the food is freshly produced. Flexible packaging include bags, pouches, shrink films, tubes, sleeves and carded packaging. All these products are processed at end users of finished rolls for which Dotec has supplied multiple solutions mainly in 24/7 production environments.
Label and narrow web
Roll handling solutions for the label printing industry are as dynamic as it's ever been. Narrow web flex printing is an industry where Dotec delivers handlers designed with long chucks that can be interchangeable. The Roll Doffing Trolley can remove batches of narrow rolls which increases output and increases safety.
The Nonwoven roll handling solutions of Dotec provide a high variety of applications for many types for Nonwoven materials. Dotec has a long history in delivering solutions to the Baby- Feminine- and Adult care production lines. Also wipes and household goods manufacturers are part of the Dotec user family.
Yarn & fabrics
Dotec’s Roll handlers for yarn and fabrics have been developed in real practice and for real practice. Wide and heavy rolls handled with Probe Type solutions, creel lines loaded and unloaded with fast and light lifting & turning devices.
Sleeves and shafts
A critical part of the roll production and roll printing are sleeves and shafts. Various weights and widths of sleeves and shafts are handled mostly by gripping type solution, horizontal to horizontal transfer, and lifting and turning. A very important factor of Dotec being a total Roll handling solution provider is taking care of all the handling related to roll manufacturing, slitting, printing and converting.

The Dotec feeling
Dotec is digital
Dotec has integrated a pneumatic motion control system. This combination of a PLC and piezo controlled valves features flow-controlled proportional pressure regulators and is powered by 24Volt. These valves allow for pressure and flow control. The operation is smooth, features and options are endless, safety is secured, down time is minimised to the maximum through remote support. The implemented industry 4.0 technology is reliable and ready for any machine to machine or other automated system.
Because of the combination of sensors and slow-start and stop functions we have added a lot of extra smoothness to our handlers. Lifting controls are proportional, tilting is fluent and our auto-level function aligns any product.
When required, settings can be changed within the process. By pushing a button or activating a sensor the weight of a product can be compensated, functions can be activated and different working modes can be set.
Safety is our standard. We take care of the users and the handled product. When the air of power is cut-off the handler will hold the load and slowly move to the bottom, a new cycle is not possible without restored air and power.
The machines are ready for industry 4.0 and are able to communicate with other machines and/or a factory automation systems. If you choose to be connected you can real-time monitor the machine for status, safety, throughput, estimated weight and other measurements and info. A fully interconnected HMI touchscreen is part of the possibilities.
All digital controlled handlers are unconnected and have a RJ45 port. This port can be connected to any computer for simple status monitoring using a web interface. When you connect a Dotec router we can establish a remote connection for remote service, status checking, parameter adjustment, finetuning and desired updates. Optionally the handler can be permanently connected to the internet or a factory network.
The in-house engineering and manufacturing team is specialised in lifting equipment for a wide variety of products while maintaining our high safety level. Dotec can deliver total handling concepts including all the controls and safeguards necessary.
Roll handling infrastructure
Depending on several factors, the decision is made whether a rail system or a jib crane is most suitable for the process.
The infrastructure is the backbone of the total system. In the design of The LiftAssist, we strive for maximum weight savings to accomplish minimum effort while moving the load from A to B.
It is essential that infrastructure components, such as rail, trolleys and bearings match these design rules.
Dotec infrastructure is designed for the 24/7 production enviroment running at high frequencies.
Dotec Jib Cranes are most suitable for short transfer processes. They provide a comfortable and ergonomic movement, exist of state of the art materials and feel smooth while moving loads. With an integrated parking bracket it secures a safe way of parking the handler when it is not in use.
Dotec aluminium rail profiles have a unique way of suspending and trolley design providing a rolling recistance ≤1% of the load to be moved.
The Dotec System
Dotec LiftAssists have very specific characteristics that are based on ease of operation, speed of work and ergonomics. The learning curve is only 10 minutes, and handling becomes a pleasure.
