Jumping Behavior of Heald in a Shedding Motion of Loom
Shedding motion Warp tension Heald Noise Weaving machine
2009/4/29
Noise in weaving mills has become very serious problem with increasing speed of weaving machine in recent years. One of these sources of noise is the collision sound of healds caused by shedding moti...
Yarn Motion in Interlacers with Various Cross-Sectional Shapes of Yarn Duct
Interlacer Shapes of yarn duct Interlaced yarn Observation of yarn motion
2009/4/15
An investigation of yarn motion in yarn ducts with various cross-sectional shapes and its effects on the characteristics of interlaced yarn is reported. Seven interlacers, which are different in the...
Periodic and Chaotic Motion in Sirofil Yarn Spinning
two-strand spinning Sirospun Sirofil chaotic motion.
2009/2/17
A dynamic model is established for two-strand yarn processing. The oscillating frequencies
of Sirofil spinning in vertical and horizontal directions are approximately obtained. The
stability and cha...
Influence of changes in Yarn Twist on the Dynamics of Yarn Motion During Spinning on a Ring Spinning Machine
ring spinning machine twisting-and-winding unit yarn twist yarn motion

Comparison of Heald Frame Motion Generated by Rotary Dobby and Crank & Cam Shedding Motions
rotary dobby cam shedding motion shedding motion weaving machine
2009/2/9
Mechanism models are introduced for rotary dobby, crank & cam shedding motions. Equations governing heald frame motion are derived. Heald frame motion curves are obtained and compared with each other....
The Geometry and Kinematics of a Toothed Gear of Variable Motion
non-circular gear geometry kinematics
2009/2/6
The paper presents a toothed gear, in which an abaxially mounted toothed wheel is the active link, while a non-circular pinion (guaranteeing continuous interaction at a constant distance between the a...
