From the Sector

BTMA member Sellers Textile Engineers is marking its 110th anniversary this year with the introduction of a new concept in carpet shearing, as the essential final step in ensuring tuft uniformity and ‘just new’ freshness in finished carpet rolls.

The company has for many years offered two options in the construction of its shearing cylinders – the first, namely the ‘strap-on’, incorporates spiral blades bolted to the cylinder body and the second, known as the ‘caulked-in’, includes spirals which are fixed very securely in a machined groove within the machine.

The new Sellers’ Hybrid Shearing Cylinder combines the benefits of both, resulting in an improved cut and finer finish, in addition to longer repeatable finishing and increased rigidity.

“The Hybrid Shearing Cylinder has all the advantages of the ‘strap-on’ spiral blade to provide a sharper and cleaner cut, along with enhanced rigidity which significantly lengthens the intervals between the necessary regrinding of the blade,” explains Sellers Director Neil Miller. “We currently have six Hybrid Shearing Cylinders operating in the field and the earliest, which has been installed in both No1 Head position, where the majority of the shearing operation and heaviest cut is performed, and also in No3 Head, where the sharper cutting angle has resulted in a much improved surface quality.”

Sellers shearing machines have led the field in carpet finishing for many decades, enabling the leading manufacturers to stay competitive by enabling the highest quality of finish to be achieved economically and efficiently.

The latest advanced features of these machines include a load cell tension control drive system, an automated touchscreen for easy operator control and fault diagnosis, an enhanced cleaning system including cylinder and blade separation and fully controllable pivoting beds. Further options include thickness monitoring, seam detection and metal detection systems.

“The Hybrid Shearing Cylinder will become standard on our latest machines and also be made available for retrofitting, to provide significant benefits to our existing users,” says Miller. “All of our equipment is designed, manufactured, assembled and tested at our plant in the UK, and as one of the few remaining European engineering companies to make all of our components in-house – with now over a century of accumulated know-how – flexibility in design allows our finishing solutions to be targeted to specific customers and their product requirements. Aligned to this is a lead in process control systems which ensure the accurate control, reliability and repeatability of the processing parameters on all of our machines.”

Sellers remains committed to providing complete finishing solutions for all carpet, tile and artificial grass products. Its range includes machines for tufted secondary backing, both conventional, powder and extrusion lamination, Wilton and Axminster products, artificial grass and foam lines, coating lines for bitumen, PVC, PU and other polymers, as well as shearing for all carpet products.

Ongoing developments on the company’s coating and drying lines have resulted in improved guiding and product tension control as well as dryer efficiency, reducing heat loss and optimising energy use. These include a re-design of the fan pressure boxes and impingement nozzles to increase airflow efficiency, modulating gas burners and introducing easy clean, accessible filters.

In addition, the proven dual zone system has been enhanced, giving a temperature differential of up to 80°C between top and bottom zones. Dryers can be heated by either gas or steam and operation and access have been simplified with controls via touchscreen and PLC.

An extensive range of ancillary equipment is available to provide maximum flexibility to cover product requirements, for both new processing lines and as upgrades to existing equipment.

“Carpet manufacturing is now based on well-established, tried and trusted processes and it’s rare for new innovations to be introduced into this sector,” says Jason Kent, CEO of the British Textile Machinery Association. “The new Sellers Hybrid Shearing Cylinder can provide a competitive edge for manufacturers which is currently being proven in the field. It’s one of a number of new innovations the company is planning to showcase at next year’s ITMA exhibition in Milan.”

Baldwin Technology Company Inc. will showcase its new portfolio of optimized LED-UV curing, IRdrying and automated cleaning solutions—all specifically designed for corrugated high-graphics printers—at the European Federation of Corrugated Board Manufacturers (FEFCO) Technical Seminar, held October 20 to 22 in Copenhagen, Denmark.

Baldwin’s FlexoCleanerBrush™ removes hickeys in four seconds and can clean plates within three to four minutes, increasing print quality and providing a cleaner, safer work environment. This automated cleaner removes fibers, debris and fine lines from printing plates at the beginning, during or at the end of a job, allowing printers to achieve optimal quality with minimal downtime—Baldwin has a proven track record of enabling significant productivity improvements for its long list of customers. Designed to replace all manual activities, this cleaning system eliminates skin contact with wash agents, increasing workers’ safety.

For wide-format flexo corrugated box printing, Baldwin’s AMS Spectral UV has engineered CorruCure™, a new generation of LEDUV technology that offers more than a 60% reduction in power consumption in an ultra-compact UV lamp head. This revolutionary solid-state curing system, designed specifically for corrugated LED printing, emits almost no heat or ozone, and accommodates width-switching. It also enables the curing of high-value decorative solutions, such as full-gloss, spot and matte coating effects on a variety of corrugated substrates, making it the ideal addition for product enhancement.

Lastly, Baldwin’s FlexoDry2™ infrared dryer, developed for corrugated flexo printing presses, utilizes patented Diamond IR lamps capable of reducing energy consumption by up to 30%, when compared to traditional IR dryers with aluminum or gold reflectors. Dramatically improved drying enhances color definition, and reduces or eliminates marking, while allowing full-speed printing. The system offers an optional integrated hot-air knife with temperature control to provide better surface drying. Taking safety into consideration, the FlexoDry2 comes with an integrated safety light curtain as standard and an optional camera vision system.

Baldwin Technology Company Inc. will showcase a new generation of innovative technologies for optimized corrugated high-graphics package printing at SuperCorrExpo, taking place in Orlando, Florida, from Aug. 8 to 12.

The FlexoCleanerBrush™ enhances the print quality and improves worker safety in corrugated printing. The system automatically removes dust and contamination from the plate in seconds during production, without stopping the press. It also performs full end-of-job plate cleaning and drying in fewer than four minutes, enabling increased uptime and sustainability. A carbon fiber core keeps even the ultra-wide FlexoCleanerBrush to a minimal weight, and ensures cleaning is stable, uniform and consistent throughout the plate’s width. Because the system is fully automatic and spans the entire width of the plate cylinder, the FlexoCleanerBrush improves safety by eliminating routine operator contact with the machine, while also reducing the risk of cylinder nip injuries and contact with wash agents.

Also on view in Baldwin’s SuperCorrExpo booth, the FlexoDry™ is a fully integrated IR drying system, specifically developed for corrugated flexo printing presses. It reduces energy consumption by up to 30 percent over standard IR dryers through patented Diamond IR™ lamps. The system delivers improved drying results because of a unique optical design that produces higher intensity for enhanced color definition, and reduces or eliminates marking altogether, allowing for high-speed and full-confidence printing.

Additionally, Baldwin will showcase LED-UV technology, designed by its AMS Spectral UV division for wide-format flexo corrugated box printing.
