Rotary Converting Platform

Intelligently Designed Machines

Whether you are a contract converter requiring a fast set-up, flexible configuration system, or a manufacturer requiring an engineered solution for your specific rotary converting needs, Preco has a solution. Preco can guide you to the correct configuration by offering the models below. These models have the quickest build times (many stocked components), mechanical and software inspection reports to guaranteeing quality, and qualified installation service once the machine is installed in your plant.

Our equipment is CE compliant and certified along with a clean room adapted for those required. We offer remote access assistance and troubleshooting technical support no matter your location. Preco has been building rotary machines for over a decade with new innovations continually developing.

Maximum flexibility and reliability.

Every Preco RCP machine uses well-organized cabinets for electronics and drives components, which are located as end-caps on the systems. This helps to provide a slim profile for machine placement and ease of serviceability. Spindle motor and reducers via electronic gearing facilitate web and taper influences for precision web tension control. The quick-change modular manifold design allows for maximum setup flexibility using die stations that can be combined or removed for space allocation.

Custom equipment is our standard.

The RCP equipment is designed to modularly integrate sub-supplier equipment and functionality. The rotary unit can be expanded or divided into sub-sections to allow specialized automation to occur within a "step and repeat" or "continuous" motion environment for accurate and repeatable insertion or deposition of such components.

Rotary Converting Platform Custom Equipment Option

Preco will build the exact width machine and type of gearing required for your legacy products to ensure tooling transformation from obsolete equipment into state-of-the-art equipment. Our customized rotary designs are driven by your equipment specification and product drawings from which the overall concept is generated. 3D modeling allows for process and design corrections during the design review phase prior to part/component machining. Debug of your machine takes place on our factory floor until satisfactory results are accomplished.

Heat-sealing solutions.

This heat-sealing unit allows easy job changeovers with an interchangeable sleeve of your seal pattern. It is as simple as removing the gear and pattern sleeve and replacing it with your next part sleeve. Changeovers can be done with 15 minutes and your right back into production. There is also the option to produce 3-sided pouches for manually filling product that requires further component insertion.

Versatility and Accuracy

This heat-sealing module can achieve temperatures up to 450° Fahrenheit (232°C) with the steel pattern tool. This module also utilizes a heat-sink material around the cylinder to ensure the heat-affected zone remains in the sealed areas. The impression roller is normally a 75-durometer silicone or Hypalon structure for high-temperature seal reliability and conformity to your materials. An optional torque-kit can be added to monitor load force to ensure the sealing tool does not deviate its compression force during operation. An Infrared feedback sensor is used to closely monitor set temperature and maintain accurate seal temperatures for your qualified process.

A secondary heat source can be added to improve sealing effectiveness and achieve faster run rates for your process. An aluminum roller is added to the inbound station which can be heated up to a maximum temperature of 350° Fahrenheit (176°C). Heat is transferred to a 40-durometer silicone roller that transfers the heat to the impression roller. This creates a dual heating application to improve your seal quality thereby generating less waste. The additional heat also allows for faster production rates. The process may wrap the web around the aluminum roller to act as a preheating mechanism offering viable alternative web paths.

Features of buying a Preco Rotary Converting Platform

1. Movable mounting plates for idler rollers

The purpose of an idler roller is to change the direction of a web. Preco’s backplane system provides idler roller capability almost anywhere on the platform. The tapped and threaded grid wall allows easy roller placement for processing of materials and for greater efficiency.

2. 1:2 Ratio of process stations to spindles

Preco found that press operators most often run out of available spindles before using up the process stations. Preco maintains an abundance of capacity.

3. Electronic device connection and registration setup

Electrical connection points on the backplane keep wires out of the path of tooling, materials and the light curtain field. Preco’s proprietary registration setup needs only the gear tooth and pattern count with a repeating mark on the web—forget homing devices or extra wires!

4. Adjustable station-mountable idlers

Long-Medium-Flush articulated idler rollers give the operator full placement control, whether close or away from the die or nip, upon entering or leaving a process station. Threaded holes on the station ensure a parallel path.

5. Quick-adjusting active web guide control

The Preco web guide alignment device provides a simple method for managing of incoming material. Three adjustments are used to assure a correct web approach angle and the equal distance of the web between the send and receive points. A fine-tune screw permits a subtle shift of the web in the Y-axis.

6. Setup-friendly control panels

Machine access during setup has been made easy. There is no need to step away to the HMI to lock down a material core, as every spindle is within reach. Apart from setup jog mode, machine speed during production can be increased with a simple turn of a knob.

7. Comprehensive human-machine interface

Whether you are a first-time user or an experienced technician, the HMI touch-screen controls of the RCP are logical and understandable. All components can be entered and monitored, along with ongoing trending of registration accuracy and roll material status.

8. Simple mounting of station accessories

You may attach a Preco-made device, or better still, an appliance that your company has created for a special purpose. The same M6 threaded holes that mount station idlers are perfect for rapid fastening of just about any fixture that is required for that next work order.

9. Full-length light curtain protection

Safety is important, but its implementation should not be an obstacle to required process adjustments. Preco provides the simplest, non-invasive solution.
