A manual beaming device: an improved method for warp winding in broadloom weaving

Abstract

Challenges with broadloom beaming that affect the weaving process and eventually the woven fabric aspect, could be as a result of the great bulk of yarns attached to the weighted box for tensioning. This project sought to construct a beaming device that maintains even tension of warp yarn at beaming by reducing the amount of yarns held together in a group to the weighted box. The study employed the Universal Research Methodology (URM). Results from interviews and observations, aided in constructing an appropriate device for beaming. In the study, relevant data was solicited from textile students and technicians at the textile section of the Industrial Art Department of IJAH, VOL. 6(3), S/N 22, JULY, 2017 142Copyright © International Association of African Researchers and Reviewers, 2006-2017: www.afrrevjo .net/ijah Indexed African Journals Online (AJOL) www.ajol.infoKwame Nkrumah University of Science and Technology which aided in designing the blueprints. The outcome of the study after 14 beaming revealed that challenges and faults hitherto encountered at beaming and weaving were largely absent. The study recommends the adaptation of this new mechanism and method of warp attachment to ensure smoother weaving and enhanced fabric quality.

Electronic warp-break detection mechanism for manual looms

“…These mechanisms aim at ensuring a smooth weaving process coupled with uniform warp tension to produce quality fabrics devoid of faults which include knots, weft loops, and loose warp (Sadik and Islam, 2014). Any tension differentials at beaming and subsequently at weaving (Frimpong et al, 2017;Gloy et al, 2015) leads to fabric faults that essentially reduce its aesthetics and price. These tension differences in the warp as opined by Cloppenburg et al (2015) and Gloy et al (2015) interrupt the weaving process.…”

“…This mechanism ensures that appropriate tension is applied on the warp to prevent breakages that would ultimately be detected using the drop wire system on power looms. For manual weaving, however, ensuring even tension at warp beaming as stipulated by Frimpong et al (2017) further limits challenges at weaving that turn to affect the finish of the woven fabric. As a result, a beaming device was developed for broadloom weaving to tension warps in smaller bulks attached to a weighted box before being wound unto the warp beam.…”

“…It is undoubtedly clear from the studies above that there is the need to maintain an even warp tension at beaming and weaving. It is worth mentioning that attaching the warp to loin sticks of the cloth beam on a broadloom with varying tension (Frimpong et al, 2017) subsequently reduces the efforts put at beaming thereby leading to several warp breakages. The broadloom (Figure 1) is identified as a weaving apparatus which features similar components on a table loom but has four heald shafts, pedals at the bottom (where the feet is used to operate it) and a wider width to weave fabrics.…”
