SPINNING A SPANISH YARN WITH A SPECIAL TWIST
High performance servodrives and servomotors from Control
Techniques are at the heart of special equipment designed to
produce bespoke yarns in a production environment in the textile
industry.
Pinter s.a. of Santpedor in northern Spain, manufactures
spinning machinery, designed to work in tandem with existing
textile machines. Every machine is to an individual design
with the capability of changing production from normal to special
yarns (and vice versa) quickly and simply. Their range
includes equipment for producing core spun yarn, slub, multicount
and multitwist yarns and a unique ‘test laboratory’, Merlin,
designed to be a research and test department encompassed in one
machine.
Core spun yarn is produced by covering an elastic, rigid or
semi-rigid filament with a natural, artificial or synthetic textile
fibre. This yarn, once woven, offers the intrinsic properties
of the inner filament, but has the appearance, texture and quality
of the outer fibre. Pinter’s core yarn system is a modular
accessory that can be fitted onto all types of short and long-fibre
spinning frames. The production process involves feeding a
continuous filament to the front drafting roller, where it is
covered by fibres delivered by the feed roving.
This positive-feed insertion system has the tension of each
roller controlled by a Control Techniques Dynamics UMD servo-motor
with resolver feedback to a Unidrive SP AC drive operating in
servo-mode. A typical machine can have four, six or eight
drives and motors, each Unidrive SP fitted with an SM-Resolver
option module, and communicating with the machine controller by
RS485, although new models will feature
Ethernet.>>>>>>>
