Abstract
A method for making concrete roof tiles includes the steps of forming a continuous elongated ribbon or layer of concrete; cutting the continuous layer into a row of spaced end to end ribbon sections having a front edge and a rear edge; precompacting the front edge of one of two adjacent ribbon sections and compacting the precompacted front edge of the other ribbon section.
Claims6
A method for making concrete roof tiles consisting of the steps of:
- (a) forming a continuous elongated ribbon or layer of concrete;
- (b) cutting the continuous layer into a row of spaced end to end adjacent ribbon sections having a front edge and rear edge wherein the front edge of each adjacent ribbon section is precompacted during the cutting step and then;
- (c) compacting and profiling the precompacted front edge of each adjacent ribbon section to form the concrete roof tiles wherein steps (b) and (c) are performed simultaneously on two adjacent ribbon sections such that a previously precompacted front edge of one adjacent ribbon section is compacted and profiled while the front edge of the adjacent ribbon section is precompacted.
