SUN Tarp gauge ( top arm load gauge ) resembles a top arm arbor of ring frame / speed frame, when replaced with a top arm arbour, directly give load in kgs. Sun tarp gauge ( top arm load gauge ) in complete kit form with all accessories such as arbours and nylon rollers from 25 mm to 75 mm for all types of drafting systems of ring frames and speed frames (as per customers’ requirements ) Sun tarp gauge ( top arm load gauge ) measure top arm roller pressure (load) in front, middle & back rollers of all types of drafting systems used today in Ring Frames & Speed Frames, such as SKF PK 225, 2025, 235, 211, 1500, 1600, 1601, 704, BM 12, 14, 15, RIETER G5/1, G6, DJ5, LF 1400, LF 1400A, SUESSEN WST UT 620, UTM 620, UTS 200, etc.| The top rollers are loaded at specific levels & thus uniformity between top arms on the same frame is maintained. In the course of continuous working, however, variations occur from the set loads which affect the quality of drafted materials. Low top arm loads results in undrafted yarn, unevenness & hence affect the strength & count CV% . Excess loads also squeeze the cots & increases the power factor of the machines. Hence, frequent methodical check up & corrections of top roller loads is necessary. The instrument is suitable for cots from 25mm to 75mm diameter with least count of 0.5 kg and max. 350 kgs. It is also suitable for wool/worsted ring spinning frames like as Cognetex, NSC, & jute spinning like Mackie, DASN, etc.
