LMW’s RAP revolutionises ring spinning at ITMA with ‘AS HUMAN PIECING.
- Lakshmi Machine Works is showcasing its Ring Frame Auto Piecing (RAP) at ITMA 2023.
- RAP is a fully automated yarn piecing system for ring spinning machines that reduces reliance on skilled labour by auto piecing the yarn, boosting productivity, and maintaining yarn quality.
- The system works efficiently with both normal ring spinning and compact spinning.
Lakshmi Machine Works Limited (LMW), India’s leading textile machinery manufacturer with a global presence, is displaying its Ring Frame Auto Piecing (RAP) at the ongoing ITMA 2023, taking place at Fiera Milano Rho in Italy. RAP, a fully automated yarn piecing system for ring spinning machines, receives information on yarn break through its YBS (Yarn Break Sensor) and travels to the particular spindle and automatically pieces the yarn instantly as a human does.
The biggest challenge faced by the spinning industry is shortage of skilled manpower, especially in ring spinning. The piecer needs to be trained and skilled to do the piecing with lesser end mending time to avoid production losses. The RAP ensures auto piecing thus reducing the dependency on manpower, LMW said in a press release.
RAP consistently works 24×7 around the year. The RAP unit receives signals from the YBS and travels directly to the respective spinning position and automatically mends the yarn as a human does. RAP captures the broken end from the package in a unique way without lifting the package, then inserts the yarn into the traveller and gets over pieced. The immediate attention to the broken end and the shorter auto piecing cycle time around 35 seconds ensures higher productivity.
RAP ensures the consistent piecing length in the mended yarn. The auto piecer also eliminates the contamination on the cop outer surface (through manual handling) which enhances and retains the quality of the yarn.
The unique design of RAP is suitable for both types of spinning technologies—normal ring spinning and compact spinning. It works with ease on all applications.
