Abstract
An apparatus and method for imprinting a hose (2) with a continuous grip enhancing texture is disclosed. The texturing device (C, C′) is comprised of a circular guide tube (8) through which the hose (2) to be textured is driven. The guide tube (8) is rotated, by a drive (4). Texturing means mounted at the exit end of the guide tube (8) are also rotated about the hose (2) as the texture is applied to the hose (2). The texturing of the hose is accomplished by at least one roller (6) mounted on a chuck (5) or by at least one scribing pen (28) mounted on a bracket (24).
Claims7
An apparatus for imprinting a cylindrical element (2) comprising a guide (8), a drive member (4), and texturing element (5, 25), the guide (8) through which the cylindrical element (2 is guided being tubular, the apparatus being characterized by:
- the drive member (4) being associated with the guide (8) to cause rotation of the guide (8), and;
- the texturing element (5,25) rotating with the guide (8) to imprint the cylindrical element (2) and the distance between the texturing element (5,25) and the surface of the cylindrical element (2) is variable.
A method of imprinting a cylindrical element (2) comprising guiding the element (2) through a cylindrical guide (8) and imprinting the surface of the cylindrical element (2), the method being characterized by:
- rotating the guide (8) about the cylindrical element (2);
- rotating a texturing element (5,25) with the guide (8) to imprint the cylindrical element (2);
- and
- varying the distance of the texturing element (5,25) to the cylindrical element (2) prior to imprinting of the cylindrical element (2).
