Cam Design | Robert L. Norton
Description:
Cam Design produced from the weave pattern is used to design the cam profile (or the shape of the cam's circumference). Each cam has a follower that moves up and down in accordance with its profile. The cam follower's motion is conveyed to the harness and hence to the warp yarns drawn in the harness via linkages between the cam follower and its harness. Due to the restricted number of up-and-down motions that a cam profile can achieve, the cam shedding method is confined to simple weave designs. Intricate weaving patterns necessitate a massive number of up-and-down motions of various sizes and timings. A reasonable amount of up-and-down motions in the cam shedding mechanism is two each. Another disadvantage of the cam shedding method is that changing the weave design necessitates replacing or adjusting a set of cams, which is time-consuming.

Another disadvantage of the cam shedding method is that changing the weave design necessitates replacing or adjusting a set of cams, which takes time. Because today's weaving machines are high-speed, this is unacceptable. Stopping such machines for a lengthy time (exchanging cam sets or adjusting cams takes roughly 20 to 30 minutes) is a premium because it reduces production. Electronic dobby and electronic Jacquard have made it possible to modify the weave pattern in a very short amount of time, or on the fly, without having to interrupt the weaving process.
