BTSR has launched what it calls a ‘revolutionary concept for bare elastane feed and control’, devised to make an impact on working practices in bare elastane applications in the seamless and circular knitting sectors.

The Italian company says its new Rolling Feeder is a “unique solution on the market, thanks to its capability to combine in a single device, the flexibility and user-friendly use of BTSR Constant Tension Feeding Technology with top product quality resulting from bare elastomeric yarns feeding at constant LFA*/speed (BTSR Patent Pending).” According to BTSR, Rolling Feeder is also easy to install, user friendly and retrofitable on any machine.

*LFA Function: exact measurement of yarn consumption (Absorbed Yarn Length) with 0.1m resolution.

Constant Tension & LFA in a single device

“Thanks to the BTSR self-adaptive electronic technology, Rolling Feeder is in fact able to work at constant tension yarn feeding during yarn ‘start/stop’ working phases (or during strong yarn pattern selections) and to automatically shift at constant LFA / speed feeding during the garment production,” says Angelo Rizzo, BTSR Sales & Marketing Manager.

“Based on derulè yarn reeling-off working concept, Rolling Feeder technology allows to eliminate yarn ‘twisting effect’ (flat yarns) and to guarantee the capability to feed elastomeric yarns at constant speed/LFA,” Mr Rizzo adds.

BTSR is keen to emphasise the uniqueness of its protected technology.

“BTSR’s Rolling Feeder System features the company’s Patent Pending ‘Double Working Modality Master-Slave’ System (derulè at constant tension / derulè at constant LFA), with the possibility to select single or multiple devices as masters and a group of units as slaves, thus guaranteeing the absolute stitch matching, preventing yarn plating faults in vanisè process and guaranteeing top quality garment production,” says Angelo Rizzo.

According to Mr Rizzo, combined with Ultra Feeder devices (masters) installed on the machine for background yarns feeding control, Rolling Feeder s (slaves) are able to work at a constant ‘stretch ratio’, thus guaranteeing fully automatic constant yarn feeding / stretching and top quality repeatability.

User-Friendly Solution

Rolling Feeder is said to be designed “for enhancing operators working life” by minimizing and simplifying labour operations, thus guaranteeing reaching of the most demanding production efficiency goals and achieving top quality production.

Innovation leader

Innovation, continuous development and customer oriented strategies are what BTSR says make it stand out from its market competitors as well as the great attention it devotes to the development of solutions meeting the real needs of the market.

The company is certified according to ISO 9001 and ISO 14000 standards, meaning that its production processes comply with the company’s Quality System. All suppliers are tested and selected and, at the same time, all the materials used in the production department are checked and guaranteed against any kind of defect.

BTSR says its research and development team includes a number of experts and specialists and no matter if the inputs come directly from the market, or if the development of a new technology originates from an idea from its R&D department, the new product will always meet the concrete needs of users.
