Working Principle :A paper plate is a plate made out of paper and often lined with
plastic to prevent liquid from leaking out or soaking through the paper. Paper plates are
traditionally made by hand in Indian villages and our aim is to convert this laborious craft into a
machine operation to make these paper plate in elegant shapes and sizes”. The base paper for
paper plates is called kraft. This kraft is coated with the thin layer of silver film. This paper is
then pass through successive stages of rolling, and then gets wounded on a roller. Then it is cut
for required dimensions. After then this paper of required dimensions is pass to the press
machine for giving required shape of plate. The operations from taking out the roller of coated
paper, cutting it for required dimensions and then transferring it to the press machine are carried
out manually.
This project work deals with mechanically operated paper plate making machine instead of
made by hand in traditional way of laborious craft. These have good dimensional stability and
are inexpensive with less time consumption.
There is described a foot-operated controller for providing discrete inputs to a machine to be
controlled, comprising: a base; a foot-receiving member for receiving a foot of a user, the footreceiving
member movably secured to the base according to at least one degree of freedom and
substantially extending within a plane; at least two switches each located at a different location
between the base and the foot-receiving member and each activatable upon a corresponding
motion of the foot-receiving member relative to the base; and a communication interface unit
for connecting the foot-operated controller to the machine and transmitting to the machine a
respective discrete command upon activation of the at least one switch, the discrete command
corresponding to a discrete input for the machine.
