A consistent drive for the textile
industry
Today's textile markets are embracing new and innovative machinery for rapidly growing products such as non-woven textiles, where fibres are fused together to form products.
Today's textile markets are embracing new and innovative machinery for rapidly growing products such as non-woven textiles, where fibres are fused together to form products such as jay clothes and automotive interiors, for example When Pneumatic Conveyors, a leading supplier of textile production lines, set out to design a metering bale opener, adding to an already comprehensive range of cost effective and efficient non-woven blending lines, it looked to Bedford based Lenze to deliver the quality of geared motors necessary to drive the machine effectively

Huddersfield based Pneumatic Conveyors has been involved in fibre preparation and blending since 1950 and currently supplies a proven product range of over 50 textile blending machines to textile markets around the world.
One particular growth market for Pneumatic Conveyors is non-woven textiles for automotive use, such as carpeting and door and roof linings, with the most appropriate solution based on factors such as raw material type, desired end product and output requirements.
The first component in the non-woven blending process is the bale opener which is arranged in small groups to handle a mix of fibre types at the start of each line.
Usually bales are synthetic man-made materials such as polypropylene and nylon.
These bales are unwrapped and the fibres delivered to the next stage of the process at a constant, but adjustable rate of feed.

Pneumatic Conveyors felt that its non-woven textile lines would greatly benefit from the introduction of a completely new bale opener that would form the input and proportioning process of the blending line, and subsequently developed the MB02 Metering Bale Opener.
The MB02 is regulated using a control system that calculates, sets and maintains the delivery rate with an exceptionally high output of 1500/2000 kg/h, dependent on width and fibre type.
It soon became apparent that a large proportion of the cost of the MB02 would be taken up by the geared motors used to drive different components within the machine.
In order to remain financially competitive, a cost effective solution had to be found, but also one that would not compromise established quality standards.
In the search for a solution, Pneumatic Conveyors also realised that a number of smaller individual geared motors would be the ideal option, as opposed to one large one, mainly due to the fact that with an AC inverter, smaller motors would effectively control the bale opener speed and therefore could be adapted to different fibre types.
Once the specifications were finalised, a number of suppliers were asked to provide a quote for the relevant motors.
The chosen solution came in the form of eight G-motion AC geared motors from Lenze Limited.
Ranging in power from 0.25kW to 0.75kW, the G-motion geared motors offer ease of mounting, compact dimensions and a 16 000 hour, maintenance free life.
Seven GSS helical worm geared motors used in the MB02 all feature hollow shaft mounting, enabling them to be bolted closer to the side of the machine, and in many cases an optional torque plate is used to prevent body rotation.
In addition a single GST helical geared motor mounts close to the machine frame.
The motors drive various components within the MB02, such as the chute roller and weighbelt conveyor, all with inverter controlled variable speed for optimum level and output control.
All parameters can be edited through a user friendly touchscreen, with the system also storing 'recipes' for regular run lots as well as fibre types and machine settings.
Each geared motor features exceptionally low backlash for exact positioning, which is the result of gear precision and optimised tooth profiles.
The G-motion geared motors typically provide 20% more torque when compared to previous models and a cubic shape helps to achieve a high power density saving space on the machine.
This higher performance can allow selection of smaller sizes for reduced costs and further space savings.
Lenze was ultimately chosen based on price and delivery times.
In addition, Pneumatic Conveyors were impressed with Lenze's range of high quality motors which have world-wide recognition and enhance the already good reputation of Pneumatic Conveyors' machinery.
Paul Lucas, Managing Director at Pneumatic Conveyors comments, "When looking for geared motors to meet our specifications, we were extremely aware that any components used in our machines had to be both reliable and cost effective, as any malfunction in the bale opener could have drastic implications for the whole of the blending line in terms of lost revenue.
Simplatroll are able to provide us with excellent quality Lenze motors which have a world-wide reputation for quality and won't let us down." Lucas continued, "In addition, Lenze are able to provide us with prompt delivery, essential for meeting tight deadlines for both the recent launch at the ITA Exhibition in June this year and future customer requests, and also came up with the most competitive prices.
We expect to manufacture about twelve MB02s each year, with a retail value of ?37 000 each." Due to the effectiveness and accuracy of the Lenze geared motors, the MB02 delivers continuous weighing, essential in forming a uniform end product, and features fast adaptation to all fibre types.
In case of breakdown or routine servicing, motor spares can be easily obtained world-wide from a comprehensive network of agents, a key factor in keeping the blending line operational.
Furthermore, the MB02 is technically superior and more reliable and accurate than other machines currently on the market, adding real value to any non-woven blending line. Request a free brochure from Lenze ...
