Karl Mayer continuously upgrades RD series machines
Dec '13
Warp-knitted spacer fabrics produced on the RD 6/1-12 and RD 7/2-12 (EL) are absolutely indispensable nowadays for use as upholstery fabrics and shoe textiles.

These breathable 3D textiles with their high compressive elasticity have become firm favourites on the market – as have the efficient, two-bar raschel machines used to produce them.

The technical features of these RD machines are continuously being improved and revamped in order to enhance the performance of this successful machine series and to adapt them to the constantly changing demands of the market.

The latest upgrade covers a whole package of specific improvements. At the request of many of its customers, KARL MAYER now offers the RD 6/1-12 and RD 7/2-12 (EL) with individual needle mounting. Replacing the needle leads with this optional feature makes it easier to change the needles on the machine itself.

Another improvement concerns the service life of the machine components. In order to protect the yarn sleys from being worn by the high loads that occur when processing monofilaments in the pile bars, these guide elements are now chromium-plated as standard.

In addition to the modifications made to both machines, some of the changes are specific to each machine individually.

Modifications made to the RD 7/2-12 (EL)

One instantly visible change that has been made to the RD 7/2-12 (EL) concerns the warp beam frame. Only one, more compact version is now available for this double-bar raschel machine.

The warp beams for ground guide bars GB 1 and GB 2 are positioned at the front support, for GB 3 to GB 6 they are fitted to the girder, and for GB 7 they are positioned at the rear support. The warp beams are handled via a new arrangement of access points.

A service platform now runs along each of the left and right front sides, i.e. along the warp beam rolls. Another footbridge runs lengthwise between the warp beams at beam positions GB 4 and GB 5.

Another modification relates to changing the pattern over when working with pattern chains. In order to facilitate this process, a pattern drum having a new divided arrangement is now available for the RD 7/2-12 (EL).

The pattern drum is made up of two separate parts. The four tracks for the pattern chains for controlling guide bars GB 1 to GB 4 are located on the front part. The movements of pile bar GB 5 and ground guide bars GB 6 and GB 7 are controlled by the pattern chains on the three tracks on the rear part of the pattern drum. A chain path having a length of 1.5 m is also available.
