Maschinery of the Graute GmbH

Opening Blending

  • Bale Opener (BO / WBO)

    The Bale Opener ensures a gentle opening of strongly pressed fiber bales as well as a thorough mixing and equalization of the starting fibers. If required, the Bale Opener can be equipped with a weighing unit, mixing belt and Continuous Mixing Opener (CMO) for metering and mixing several fiber types.

  • Continuous Mixing Opener (CMO-W2)

    The Continuous Mixing Opener guarantees already at the first opening point a very good mix of the different fiber types as well as a gentle dissolution of the fiber flakes by continuously feeding of two fiber types. Through this newly developed mixing machine, the production capacity of the opening can be significantly increased and the mixture can be significantly improved. The use of large, space-consuming mixing boxes is no longer necessary.

  • Large Volume Blender (LVB)

    The Large Volume Blender is used to buffer already opened fibers to compensate for fluctuations in the production process. During buffering, the fibers are also mixed and homogenized again.

  • Micro Tuft Opener (MTO / MTO-M)

    The Micro Tuft Opener ensures optimal quality of the end product through a gentle dissolution of the fiber flake down to the individual fiber and a thorough mixing of the fiber. For large working widths (≥ 2 m), a retractable version (MTO-M) was developed to considerably simplify maintenance, cleaning and minimize downtimes.

  • Pre Opener (PO)

    The Pre Opener ensures a continuous feed of the following machines with fiber material and compensates for fluctuations in delivery of the opening line. Two feed rollers and one opener roller also pre-open the fiber.

Carding

  • Card Feeding Unit (CFA)

    The Card Feeding Unit forms a uniform fiber mat from the injected fiber flakes and for the following carding machine. The adjustable profile forming device of the CFA ensures that each point of the working width of the following machine is covered with the right amount of fibers.

  • Cutting Device (CD)

    The Cutting Device limits the fiber mat before the web formation by a double-sided, adjustable edge cut. The web width can be adjusted individually and the edge trimming is fed back to the process without fiber damage.

  • Weighing Plate System (WPS)

    The Weighing Plate System monitors the throughput and ensures automatic weight stabilisation in the production direction.

  • High Performance Card (HPC)

    The High Performance Card can be configured individually according to your needs. The modular construction and the different delivery technologies (parallel web, randomized web, condensed fleece, randomized condensed web) guarantee the optimal solution for your product. Folding trays and the ability to retract the individual sections simplify maintenance, cleaning and minimize downtime. The use of a high-speed output also enables production speeds of up to 250 m/min.

  • Air Lay Card (ALC)

    The Air Lay Card creates a very good MD - CD ratio due to the aerodynamic fleece formation. Almost all types of natural and chemical fibers can be processed into non-woven fabrics with a weight up to 300 g / mm². Folding trays and the ability to retract the individual sections simplify maintenance, cleaning and minimize downtime.

  • Random Card (RC)

    The Random Card combines the advantages of aerodynamic web formation with mechanical web removal by rollers. In addition to chemical fibers it can also process 100% natural fibers such as cotton. The isotropic arrangement of the fibers allows for improved strength in the final product. Folding trays and the ability to retract the individual sections simplify maintenance, cleaning and minimize downtime.

  • Air Web Former (AWF)

    The Air Web Former is a machine for the production of voluminous thick nonwovens weighing up to 5,000 g / mm². Almost all types of natural and chemical fibers can process. The maintenance-friendly design and the ability to retract the individual sections simplify maintenance, cleaning and minimize downtime.

Webforming

  • Cross Lapper (CLB)

    The Cross Lapper impresses with its high smoothness due to the particularly highly stiff construction. A very low mass of moving parts, for example, by using rollers made of glass fiber reinforced plastics allows very short increasing and braking times. The profile forming system ensures precise control of the web weight over the entire laying width.

  • Web Drafter (WD)

    The Web Drafter has the task to reorient the fibers and to stretch the entire web. Multiple stretching points allow to pull the material apart very gently so that the line speed and the throughput can significantly be increased.

  • Condensing Roll System (CRS)

    The Condensing Roll System was specifially designed for an extension to a Rieter C60 / C70 card. It increases the grammage and improves the MD - CD ratio by reorienting the fibers. The Condensing Roll System with a Rieter Card is often used in conjunction with an Air Lay Card, in order to be able to produce cost-effective multilayer webs. A particular advantage of this is that with a 3-layer fleece, such as in the production of cotton pads, the middle layer can be equipped with up to 70% recycled fiber with the help of the Air Lay Card.

Recycling

  • Continuous Mixing Opener (CMO)

    The Continuous Mixing Opener has the task to open already solidified nonwoven residues and edge stripes and to feed them back into the process.

  • Edge Stripe Opener (ESO)

    The Edge Stripe Opener has the task to open already solidified nonwoven residues and edge stripes and to feed them back into the process.

  • Carding Opener (CO)

    The Carding Opener can be used to re-open very strong solidified materials (edge stipe, deposit rolls, etc.) which previously had to be disposed of at a cost. These materials can then be feed back into the process. This results in a considerable savings potential since no disposal costs are incurred and fewer new fibers have to be used to produce the product. As a result, the payback period of the carding opener is usually well below one year. Folding trays and the ability to retract the individual sections simplify maintenance, cleaning and minimize downtime.
