Rieter’s component business comprising of the 4 companies Bräcker, Graf, Novibra and Suessen is a leading global provider of components for all spinning technologies. The brands have a joint display of products and solutions at ITME 2016.
BERKOL
The highlight at ITME is the BERKOL multigrinder. The entire range of top rollers and long cots used in a spinning mill can be processed on only one single machine. Any execution of center guided top roller is ground fully automatically on the BERKOL multigrinder. With this system you achieve a grinding capacity of up to 150 top rollers per hour, while you can leave the BERKOL multigrinder unattended to for as long as 30 minutes.
In addition to the automatic grinding of top rollers, with the BERKOL multigrinder you also benefit from the semi-automatic grinding of long cots with up to 490mm axis length. Thanks to these two applications on one and the same grinding machine, you can reduce the number of grinding systems required in your mill.
On the occasion of strengthening the assortment of BERKOL cots, Bräcker launches with BERKOL 63 a new cot dedicated to spinning compact yarns. It enables constantly outstanding yarn values throughout the entire lifetime. Excellent fibreguideance is given due to the softness of compound without showing lapping tendencies. Besides the introduction of the new cot, the other types were optimized to offer highest market standards in terms of price / performance ratio. Samples are ready for shipment to your mill in order to verify their quality and to benefit from the upgrade of the BERKOL assortment.
GRAF competence as a complete system provider
Graf, located in Rapperswil near Zurich, is the leading manufacturer of clothings for flat cards, roller cards and combs for combing machines. As a complete system provider, Graf offers a comprehensive package from the product and technical advice through to service and service equipment.
EasyTop
Flexible clothings are one of the key components in a carding machine. To ensure an evenly high quality of the carding sliver, they have to be replaced regularly. When the personnel are doing the replacement, the carding machine has to be stopped. To keep these down-times as short as possible, Graf now offers a new flat system which can reduce the stoppage time by 70 per cent. The so-called EasyTop is used for flat clothings with magnetic adhesion technology.
The flats, equipped with a metal carrier, are attached securely and precisely by a high energy magnet. They resist even high carding forces and guarantee high reliability in operation.
The replacing of the flat tops is very simple: They can be removed and reattached manually. There is no need for additional special tools. After placing the EasyTop on the flat bar, the high energy magnets automatically assure the correct positioning. The flat bars are mounted on the carding machine, which can continue the production immediately after setting. The reduced stoppage increases the cost-effectiveness. The flat tops do not have to be equalized in a flat workshop, which reduces the costs even further.
The EasyTop system can be used for flat bars with magnetic attachment from all manufacturers. The flat tops are currently available for working widths of 40” and 51” (60” in progress) and in the well-known setting patterns for all major applications.
Novibra’s spindle technology leadership
Spindles in modern ring spinning machines reach speeds of up to 25,000 rpm. In these high-speed applications energy consumption is an important issue. Novibra is now introducing the new LENA (Low Energy consumption and Noise Absorption) high-speed spindles. The LENA design has been developed from well-proven Noise Absorbing System Assembly (NASA), which ensures minimum neck bearing load, vibration and noise level at high speed. The unique wharve diameter of 17,5 mm and the footstep bearing diameter of 3 mm lead to a lower energy consumption. LENA is designed for tube lengths of up to 200-210 mm.
Another new product presented at ITME is the clamping and cutting crown CROCOdoff, which is also available as the version CROCOdoff Forte for coarse yarns. The crown is operated by the spindle speed and has been designed for machines with auto doffer. The improved design of the “teeth” guarantees a reliable clamping and cutting of the yarn.
In addition, the CROCOdoff reduces the risk of yarn breakage during start-up, decreases energy consumption, minimizes material loss and reduces maintenance. CROCOdoff is suitable for use with new machines as well as an upgrade for the existing machines.
Suessen’s new components for ring & rotor spg.machines
In ring spinning one of the highlights is the EliTeCompactSet, a compact spinning system, which can be installed on nearly all types of ring spinning machines. The system includes various innovations resulting in better yarn quality and increased productivity. An example is the EliTube Concept: as the fibre path within the drafting system is off-centred and the slot inclination is varied from left to right depending on the machine side, the use of top roller cots and aprons can be doubled. The main goal of this and the other innovations is increasing lifetime of the components and reducing maintenance costs.
The EliTeCompactSet can be equipped with the optional EliTwist enabling production of compact two-ply yarn on ring spinning machines. EliTwist is highly suitable to spin two-ply core yarns.
Suessen also presents various new premium parts for rotor spinning machines. The new TwistTrap Navel is a modified navel with a patented twist-retaining element. The navel, which is applicable to all types of SpinBoxes, provides an additional false twist, which results in better spinning stability. The production increases by 10-15 per cent due to the possible twist reduction.
Another new premium part is the PS7 TwinDisc. There is substantially less flexing work between rotor shaft and disc, as the width of the disc is reduced from 10 mm to 7 mm. Due to the lower energy consumption – up to 11 W per spinning unit is possible depending on the rotor speed – the pay-back period of this innovative component is very short..
