Abstract

A travelling mold has mold block sections (3) which are driven around an endless track (1, 2). The mold has a drive system including a first drive component (S) which drives the mold block sections in abutting positions with one another to a second component (7) in the drive system which accelerates and separates the mold block sections (3) and which then decelerates and regroups the mold block sections in their abutting positions before the mold block sections (3) are returned to the first drive component (S). This separation and regrouping of the mold block sections (3) eliminates the necessity of having a complete chain of abutting mold block sections (3) completely around the mold.

Claims

AMENDED CLAIMS [received by the International Bureau on 8 November 1995 (08.11.95); original claims 1-4 amended; remaining claims unchanged (2 pages)] THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A travelling mold having mold block sections which are driven around at least one endless track, said mold having a drive system including a first drive
component which drives the moid block, sections in abutting positions with one another to a second component comprising auger means in said drive system, said auger means
accelerating and separating said mold block sections and then decelerating and regrouping said mold block sections side by side with one another before returning said mold block sections to said first drive component.
2. A travelling mold as claimed in claim 1 wherein said mold block sections include a first set of mold block sections and a second set of mold block sections and said at least one endless track includes a first endless track on which said first mold block sections are mounted and a second endless track on which said second mold block sections are mounted, said first drive component driving said mold block sections to form a mold tunnel in which said first set of moid block sections meet with said second set of mold block sections, each of said first and second tracks having a return path away from said moid tunnel and the return path for each of said first and second tracks being provided with [at least one auger said auger means having an upstream end, a downstream end and an elongated body portion between said upstream and said downstream ends of said auger means, said auger means being rotatafcle and having a helical thread therealong and said helical thread having a matching tight winding at said upstream and said downstream ends of said auger means with a wider winding of said thread being provided over said elongated body portion of said auger means and guide means for guiding said mold block sections lengthwise of said auger means.
3. A travelling mold as claimed in claim 2, wherein eaid auger means comprises a first set of spaced apart matching augers along said return path of said first track and a second set of spaced apart matching augers along said return path of said second track, said first set of augers being matched with said second set of augers.
4. A travelling mold as claimed in claim 3 wherein said augers are located above and below said mold tunnel.
5. A travelling mold as claimed in claim 3, wherein said mold block sections in both said first and second tracks move horizontally to and from said mold tunnel.
6. A travelling mold as claimed in claim 1, wherein all of said mold block sections are mounted in a single track.
