Modern Developments in Spinning

Compact Spinning Protruding fibres fromrepparttar body of yarn, known as hairiness, is a characteristic feature of staple fibre yarns. This givesrepparttar 133498 yarns and fabrics made from them a softer and comfortable feel. Atrepparttar 133499 same time, hairiness has some undesirable effects as pointed below 1.Full ralisation of strength of fibres is not realised as part ofrepparttar 133500 fibres are not integrated inrepparttar 133501 yarn 2.Rough feel is given to yarns 3.Variation in hairniess is a source of weft bars and warp way streaks in fabric. 4.Long protruding hairs from yarn contribute to multiple breaks in weaving and fabric faults like stitches and floats. Compact spinning is designed to reduce hairiness in yarn. In traditional spinning fibres inrepparttar 133502 selvedge of strand emerging from front roller nip do not get fully integrated into yarn because of restriction to twist flow byrepparttar 133503 spinning triangle. These fibres therefore show up partly as protruding hairs or wild fibres. To overcome this effect,repparttar 133504 spinning triangle is nearly eliminated in compact spinning by incorporating a condensing zone after main drafting zone. The condensing zone has a revolving perforated apron with suction underneath. The fibres are collected onrepparttar 133505 perforated track and thus get condensed. The width of strand under front roller nip is substantially reduced and this enables twist to flow right up to nip. As a result hairiness is substantially reduced. Compact spinning systems are offered by Rieter(Comforspin), Suessen(Elite) and ITV-Zinser among others. Benefits claimed from comfort spinning are

Part Program Selection on a Fanuc Power Mate with a Selector Switch

Written by ControlOn

Synopsis: Fanuc Power Mate (Models D, F) has an option called “Workpiece Number Search”. Using this option,repparttar PMC can initiaterepparttar 133497 execution of a specified part program. This is especially useful in cases whererepparttar 133498 Power Mate is used to control special purpose machines that produce a known set of components. Such applications are found in batch production factories.

How it Works: To synchronizerepparttar 133499 PMC and CNC functions, there is a communication area inrepparttar 133500 Fanuc Power Mate whererepparttar 133501 PMC & CNC exchange signals. These are a set of bytes and there are two areas namely:
