Unique Traversing Mechanism
The spooling equipment manufactured by Double R Controls uses our unique traversing winding mechanism that makes no side contact with the material, reducing the possibility of damage during the spooling process.
Equipment is available for spooling / traverse winding trims, either coreless or on a cardboard or plastic core.
Wide Range of Materials
The techniques used on equipment manufactured by Double R Controls enable us to process both adhesive and non-adhesive materials.
Computer control is a standard feature of our spooling equipment that enables the spooling characteristics to be saved and downloaded at a later date, therefore reducing downtime.
Concept proof by demonstration
We have a wide range of equipment in our factory to demonstrate your product being spooled.
For small diameter spooled packages, facilities are available for automatically unloading the finished spools. This technique is particularly useful when processing 6,000 and 12,000 metre long x 1.6 mm to 6 mm wide tear tape spools.
Typical Application for High Productivity Spooling
With the novel and unique techniques advocated by Double R Controls, our equipment is capable of processing materials over the width range of 0.17 mm (typically metallised polyester) up to a width of 150 mm (typically a foam material for diapers).
The equipment is also capable of spooling plain paper, which is particularly fragile and cannot accept any side contact. All industries can benefit from spooled products if their process is using material over the width range 0.17 mm to 150 mm.
Both adhesive and non-adhesive materials can be spooled on open cores or, if required, flange cores (bobbins).
Electric Infrared Equipment for use in Industrial Processes
Short wave, medium wave fast response, medium wave and long wave heater enclosures are manufactured to suit the particular process requirements.
Control systems are manufactured in-house to operate in conjunction with the particular type of infrared equipment used.
Industrial Process Simulator
A standard industrial process simulator is available to allow customers to evaluate the optimum wavelength of infrared energy for their particular process.
Infrared Blown Bulb Module
To accelerate the curing process, in many instances equipment is only required to simulate a sunny day. With the use of the specially frosted face blown bulbs, low intensity short wave infrared energy can be used to optimise the process requirements.
A short wave, high intensity muffle heater is a standard piece of equipment for processing products of small diameter.
Infrared energy can be used in virtually any industry that requires heating, drying or curing of a process. Infrared energy can be used on both regular flat products as well as irregular products, by using the correct control philosophy.

A Frame Folders
CF125 A-Frame Folder
A precision machine robustly constructed for maximum rigidity. The 40 mm thick side frames are precision ground and jig bored for optimum accuracy, and the side frames are held together by spigot located stay tubes to obtain the rigidity.
The unwind section of the unit, which is manufactured from 40 mm thick side frames and held together by spigot located stay tubes, support the unwind reel on a pneumatic expanding mandrel. The mandrel has deep grooved bearings fitted to it and is retained in position by quick release eccentric clamps. The unwind carriage with integral guiding roller, is supported on 40 mm diameter linear ball bushings for optimum guiding efficiency. The pneumatically operated disk brake is incorporated into the unwind carriage assembly, and is coupled to the unwinding reel by a nylon drive dog.
A DC motor driven hardened ball screw is an integral part of the unwind carriage to optimise the guiding system. An error signal from a photoelectric edge detector provides the input signal to the guiding control electronics, which converts this signal to drive the DC motor, which in turn corrects the material alignment error. The material, on leaving the unwind carriage and guiding roller, passes around a tension sensing compensating roller and then over two rollers providing an inspection path.
A dancer roller technique is used to eliminate any tension changes in the material through the machine due to lobbing unwinding reel. The precision A-Folding Frame, which can be air lubricated or covered with a low co-efficient material, folds the material in the required position, which is maintained by the edge guiding system.
The folded material passes between two dynamically balanced rollers and then around a further two rollers, before leaving the A-Frame Assembly to enter into the next process. All rollers are dynamically balanced to ensure that no vibration occurs even when operating at high speeds. The complete A-Frame unit sits on a bed plate that is robustly constructed and ground to maintain the alignment accuracy of the complete unit.
The bed plate is designed with suitably sized slots for accepting the forks of a standard fork lift truck to enable the complete unit to be easily positioned behind various equipment to increase the versatility of the assembly. When used in conjunction with a DRC Rewinder, all electrical and pneumatic signals are provided by the Rewinder.
The unit can be supplied as a stand alone unit, which would then have all necessary electrical signals provided from within the A-Frame Folder. It would then only be necessary to connect the appropriate electrical and pneumatic supplies.
