MACHINERY DEVELOPMENTS

SPINNING
Gravity Traps for Blowroom – efficient removal of ginned and unginned seeds and other heavy foreign matter without harsh mechanical treatment; saves card clothing from damage.
BTRA Comb Bar for Blowroom – enables reduction in lint loss by 10-19% in bladed beater and 6-9% in Kirschner beater.
Duo-flat Carding System for Conventional Cards – helps to raise the production of conventional flexible clothed cards by 30 to 50% in the transitional sixties.
Modified Fibre Retriever for Cards – reduces lint loss in the licker-in region.
Attachments on open end spinning machine – to produce fancy and speciality yarns.
Stop-motion for Reeling Machines – assures uniform length in reeled hanks.
Stop-motion for Doubling and Twisting Frames – increases machine allocation and reduces yarn waste.
A Prototype Air-jet Spinning Machine – fabricated and commissioned.
WEAVING
BTRA has developed a number of attachments/systems (electromagnetic linkages) to eliminate imperfect mechanical linkages of pirn change automatic looms to reduce fabric defects. All the systems are maintenance free and assessment of functioning of all the motions can be made merely through visual observations and without stopping the loom.
Opto-electronic sensors for retrofitting on stop motion bars of warping machine with V-creel.
Electronic let-off motion for conventional automatic pirn changing loom to enhance fabric quality meant for export.
CHEMICAL PROCESSING
Electrode System for the `Novel Electrolytic Process’ – inexpensive attachment for jiggers, continuous dyeing ranges, etc., saves upto 40% sodium hydrosulphite in vat dyeing.
Laboratory Jig Hand Operated Hank Dyeing Machine for Use in Handloom Sector.
