Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
Apparatus for continuously mixing, molding and curing synthetic resinous materials to produce a continuous elongated product therefrom comprising: a. mixing and dispensing apparatus for one or more chemicals in fluid form contained in a mixing chamber to produce a compound to be dispensed; b. molding and curing apparatus operatively associated with said mixing and dispensing apparatus to receive said compound as it is dispensed, said molding and curing apparatus including a pair of complementary mold belts arranged to form at least one mold cavity and into which said compound is dispensed and within which it is cured, said molding and curing apparatus including guide means for said mold belts, said guide means operatively associaed with said mold belts to form said cavity therebetween, means for driving the guide means associated with each of said mold belts at a speed substantially equal to the speed of said mold belts, heater means associated with each of said continuous mold belts to retain said mold belts at a predetermined temperature; and, c. means for monitoring the speed of said mold belts and operable to energize said heater means when said mold belts have attained a pre-determined speed.
Claim 2
Dependent Claim
194 words
Apparatus for continuously mixing, molding and curing synthetic resinous materials to produce a continuous elongated product therefrom comprising: a. mixing and dispensing apparatus for one or more chemicals in fluid form contained in a mixing chamber to produce a compound to be dispensed; b. molding and curing apparatus operatively associated with said mixing and dispensing apparatus to receive said compound as it is dispensed, said molding and curing apparatus including a pair of complementary mold belts arranged to form at least one mold cavity and into which said compound is dispensed and within which it is cured, said molding and curing apparatus including guide means for said mold belts, said guide means operatively associaed with said mold belts to form said cavity therebetween, means for driving the guide means associated with each of said mold belts at a speed substantially equal to the speed of said mold belts, heater means associated with each of said continuous mold belts to retain said mold belts at a predetermined temperature; and, c. means for monitoring the speed of said mold belts and operable to energize said heater means when said mold belts have attained a pre-determined speed.
Claim 3
Dependent Claim
43 words
The combination according to claim 1 further including automatic cutoff means connected to said molding and curing apparatus and adapted thereon to receive said elongated product from said mold belts to effect cutting of said continuous elongated product into strips of predetermined lengths.
Claim 4
Dependent Claim
52 words
The combination according to claim 2, in which control means are provided effective to control said mixing and dispensing means in correlation to operation of said molding and curing apparatus and automatic cutoff means whereby the entire apparatus is shut down if predetermined parameters for operation of the apparatus are not met.
Claim 5
Dependent Claim
33 words
The combination according to claim 3, in which said control means comprises a plurality of sequentially operable control circuits required to be activated in a predetermined order to effect activation of the apparatus.
Claim 6
Dependent Claim
54 words
The combination according to claim 3, in which said control means comprises a plurality of sequentially arranged control circuits interdependently associated to require activation in a predetermined sequence and including switch means in each control circuit whereby a failure in any given control circuit results in deactivation of all control circuits previous in sequence.
Claim 7
Dependent Claim
37 words
The combination according to claim 1, in which means are provided operatively associated with said heater means to sense the temperature of said mold belts and control energization of said heater means in response to said temperature.
