Compressor Applications

Power looms

Typical power looms use a low volume of air. Those doing denim spinning or operating medium-size PFY plants need 500 - 1,500 cfm. Large, integrated facilities and texturing units require the highest volume, 2,000 - 40,000 cfm.

Gardner Denver not only builds reciprocating and rotary screw compressors, air treatment systems and automatic monitoring technology to serve all those air requirement ranges, but also continues to develop the latest innovations in compressors to support wise capital investments.

Blower and Vacuum Applications

Draining and drying of dyed carpeting

After being dyed, carpeting must be washed and rinsed in clear water. In this process the carpet becomes soaked with water, which must then be extracted gently and economically.

To do so the carpeting is passed over a suction roller with an adjustable suction slot. A vacuum pump connected to this suction roller draws air through the slot, thereby extracting about 80% of the water remaining in the carpet. The steady stream of air ensures a gentle treatment of the material. The continuous flow of water is easily removed and subsequently eliminated along with the operating liquid.

Fabric cutting tables

To facilitate the positioning of heavy bolts of cloth for processing, an air cushion is generated in the cutting table via a perforated plate. Once the bolt is positioned, a vacuum holds the cloth in place for processing on the table top.

Knitting machines

Textile dirt occurs at the fabrication of technical textiles. This dirt is extracted into a reservoir by the vacuum of a side channel blower.

Power air looms

To make it easier to change filling bobbins, the starting ends of the threads on the filling bobbins stacked in the magazine are automatically drawn in and tensioned. Once all the yarn on a filling bobbin has been used, the starting end of the thread is cut, extracted and placed in a thread receptacle in front of the blower. When the weaving process is completed, the edge of the fabric is vacuumed to prevent leftover thread from being dragged into the shed.

Sock knitting machines

During the knitting process, compressed air is applied to hold the finished portion of the sock inside the stocking tube so that the knitting needles can work freely. Stray threads are vacuumed away. When knitting is finished, the socks are sucked out of the tube and into a bin by means of a compressed air line, which is connected to the receiving bins for the individual knitting machines.

Steam treatment of yarn

Yarn in spinning machines is wound around spools, giving the thread a curled profile. To further process the yarn, however, the threads must be straight. For this purpose, steam is applied to the yarn to break the alignment of the material molecules and smooth out the fiber structure.
