Course Outcomes:
Students will be able to achieve & demonstrate the following COs on completion of course based learning
- Prepare the “Pirn” using a weft preparatory machine with the required specifications.
- Set the mechanisms under the primary motions of the weaving loom according to the given fabric sort.
- Adjust the let-off and takeup mechanisms to produce fabric with the required pick density.
- Maintain auxiliary motion for weaving defect-free fabric.
- Identify various fabric defects and analyse the causes and remedies of the same.

Suggested Micro Project / Assignment
Self learning
- Gather information on possible defects in the woven fabric and their relative proportion from the industry.
- Explore the timing cycle of primary motions on the automatic loom from various resources.
Seminar
- Positive let-off and take-up mechanism
- Types of shuttles used in power and autoloom
Micro project
- Conduct an experimental investigation to demonstrate the combined effect of varying the number of teeth on standard and change wheels in the take-up mechanism on picks spacing in fabric and present the findings
- Establish the relation between the picking force and speed of the shuttle in the power loom and present the findings in terms of graphs and correlation equations
- Design the negative shedding cam to produce the required weave and demonstrate its working through presentation/ working model
Assignment
- Collect and compile the defect samples frequently observed in woven fabric during manufacturing. Name each and report possible causes and remedies.
- Inspect power looms of diverse widths within the weaving industry and document their respective sley eccentricities.
- Report the current practice in the power loom industry to maintain uniform tension on warp from full to empty beam.
Laboratory Equipment
- Pirn winding machine with at least one head 1
- Defective fabric samples 5
- Power loom with at least 4 heald frames. All
- Tools like a spanner, gauges, scale, calipers All
