Tufting-machine-revision and -conversion

Depending on the machine-condition a revision mainly includes the replacement of bearings, bronze-bushes and bolts in all shaft sections and the replacement of push-rod-bushes and push-rods as well.

Changings of the machine-gauge, conversions from loop-pile into cut-pile or vice versa, additional fitting of mechanical equipments - i.e. pattern-attachments or yarn detectors - depending to the manufacturer-type, as well as a complete exchange of electrical equipments we define as machine-conversion.

Machine-Conversion: New mechanical Sliding-Needle- barattachment with Jumbo-CAM, fittet to a cut-pile-machine.

(30 years experienced) Broken end Yarn-detector FST II with drop-wires, fitted to a cut-pile-machine. In case of a broken yarn-end the drop-wire will stop the machine, when it falls between the photo-cell-area. The detection of broken Yarn-ends will take place for every single-end and not for groups of yarn.

High-performance  carbon-fibre-reinforced plastics (CFRP) for tufting-machines

Two integrally manufactured needle and looperbars are regarding in state of the art precise metal profiles whose dimensional accuracy are from enormous importance at the active point  of tuftingmachines.

Especially in metal bars the low material-elasticity and the heat expansion have a negative impact on the precise distance of loopers/hooks and the needles, which could bring the effect , that the hook/looper works on the wrong side of the needle, as well as opposite to this an occurrance of loops could be the result (loopers/hooks are to far from the needles). So far the bars react sensitive to temperature fluctuations, and these vulnerabilities can either be a result by fluctuations in ambient temperature, but also by fluctuations in the friction temperature. To ensure a secure accuracy between the needles and hooks/loopers the goal must be to eliminate or minimize the expansion factor, that will  not only increase the  lifetime of needles and loopers, but also ultimately secures the quality of the carpet and leads to a secure operation.

Carbonfibre reinforced Plastics (CFRP), are proven lightweight materials  which are distinguished by their extremely high strength and rigidity. Low density, excellent damping properties and a high resistance to impacting, in combination  with  minimized thermal expansions,  are completing the material characteristic profile.
Minimal thermal expansion, reduced bar-weights as well as high material stiffness and material strength allow the increasing of machine-speeds on one hand  and are leading to a damping of mechanical machinevibrations on the other hand. Impacts on machine spacing between needles and loopers/hooks caused of fluctuations in ambient temperature governed by seasonal or daytime factors, as well as the fluctuation of material temperature caused of friction between gauge-parts will have no influence on the running of the machine. A permanent readjustment of the bars after periods of stops is no longer required.

Chainstitch-Tuftingmachine for the production of dust mops

The chainstitch primarily has the function to fix the pile-yarn on the backside by itself, without using any coating, that normally is usal for a solidification of the pile in the range of tufting. To that extent the use for dust mops is recommended, because coating would lower all characteristics of a dust mop as an cleanig-device (i.e. water resistance, suppleness etc.). Other applications are conceivable, i.e. in such textiles, in that a coating would lower the performance characteristics (for enlargement click the thumbnail)

It is possible to work 3 mop-strips parallel with this machine, respective to the individual mop-width but in a total working-width of 500 mm. The machine produces a loop-pile-height of 22 mm.
Behind the rear spike-roller the individual tuft-sections are cut to the width that is necessary for all subsequent treatments. (for enlargement click the thumbnail)
