|The most widely adopted solution is the STAGGERED grid model.
This is adopted for the following requirements:
a) very high density brushing surface
b) very uniform brushing surface
The PARALLEL grid is used in the following cases:
a) the brush must be able to discharge debris easily without becoming clogged
b) mechanical parts must be able to transit between the tufts
c) the brush must be cut into sections by the user
The SPIRAL grid pattern is used for roller brushes in the following cases:
a) the brush is required to route treated material to one side
b) the brush must come into contact with the workpiece surface gradually and delicately. The spiral pattern may be composed of several coils each of which composed of several rows of tufts.
