Process and apparatus for forming dual hose cuffs, hose, e.g. corrugated hose, provided with cuffs, hose cuffs and hose, e.g. corrugated hose, provided with cuffs formed by such process
View Patent ↗Apparatus and process for forming dual hose cuffs for being split to provide one hose cuff on one length of hose, particularly a corrugated hose, and another hose cuff on another length of hose, particularly a corrugated hose. Cuffs, or hose cuffs, formed by such process. Hose, particularly corrugated hose, provided with cuffs formed by such process.
1. Apparatus for forming dual female hose-cuffs, comprising:
a pair of dual cuff blocks for being placed in opposition to provide opposed asymmetrical dual female cuff forming surfaces providing a generally cylindrical asymmetrical dual female cuff forming chamber having a leading diameter, middle diameter and a trailing diameter, said middle diameter being larger than said leading diameter, said trailing diameter being larger than said leading diameter, and said trailing diameter being smaller than said middle diameter.
2. The apparatus according to claim 1 wherein said apparatus is for forming dual locking female hose-cuffs, wherein said chamber is a generally cylindrical asymmetrical dual locking female cuff forming chamber having a leading end having said leading diameter and having a trailing end having said trailing diameter, wherein said chamber has a central annular recess including a middle portion having said middle diameter, a first intermediate annular recess intermediate said central recess and said leading end and a second intermediate annular recess intermediate said central recess and said trailing end, said first intermediate annular recess having a first intermediate recess diameter and said second intermediate annular recess having a second intermediate recess diameter, said first intermediate recess diameter being larger than said leading diameter, smaller than said middle diameter and smaller than said second intermediate recess diameter, said second intermediate recess diameter being smaller than said middle diameter and larger than said trailing diameter, said central recess having a leading central recess diameter and a trailing central recess diameter larger than said leading central recess diameter.
3. The apparatus according to claim 2 wherein said central recess has a tapered leading surface and a tapered trailing surface, and wherein said tapered leading surface and said tapered trailing surface have a common taper angle.
4. The apparatus according to claim 3 wherein said common taper angle is about 45°.
