Abstract: A method is provided for cutting a glass duct, whereby the glass duct can be cut off completely straight. In this method, the coating layer is first cut through all round at the axial location of the fiber where the fiber is to be notched before the notching and subsequent breaking off of the glass duct. To enable the use of this method for glass ducts of varying diameters, the glass duct can be retained in a fixed position during cutting, while a cutting member, as well as a counterpressure surface for the cutting member, are moved all round the glass duct. Because glass ducts of a relatively small diameter are pressed further sidewards by the cutting member than glass ducts of greater diameter, this method effectively limits this sidewards displacement to prevent the glass ducts from breaking in an unintended manner.

Abstract: A process for manufacturing holes on the circumference of a hollow section situated in an internal high pressure forming tool uses the action of a punch integrated in the forming tool. A desired breaking point is formed on the hollow section, which follows the edge contour of the operating face of the punch; and after the withdrawal of the punch, the hollow section material surrounded by the desired breaking area, acted upon by internal high pressure, is extracted from the hollow section from the inside to the outside, forming a hole. In order to produce holes on the circumference of hollow sections, in which the shape of the outer circumference of the hollow section is maintained, the wall of the hollow section is weakened to form an unstable thin area. The punch penetrates into the wall of the hollow section at an internal high pressure which corresponds to the forming pressure for forming a hollow blank inserted in the forming tool.

Abstract: A grout removal tool includes an adapter having a replaceable cutting blade mounted thereon. The adapter is configured to be installed within a common reciprocating saw. The adapter has a proximal attachment end for attachment to the saw, an elongated proximal leg extending from the proximal attachment end, and an elongated distal leg extending from the proximal leg at an angle to terminate in a distal end whereupon the cutting blade is attached. When the proximal attachment end of the adapter is installed within the reciprocating saw, the cutting blade reciprocates in a parallel plane beneath the plane in which the proximal leg reciprocates. When the cutting blade is reciprocated across a grouted work surface, it results in a high rate of grout removal with low dust dispersion.

Abstract: A steel rule die for cutting cloth and synthetic materials. The cutting die includes a primary substrate and a plurality of cutting units that are removably attachable to the substrate in such a manner that they are easy to adjust, remove and replace. The cutting units include secondary substrates with lengths of steel rule attached to them. The cutting units are secured to the primary substrate. Each steel rule is fixedly attached to a secondary substrate that is substantially harder than the primary substrate. The secondary substrate distributes the cutting load applied to the rule over a large surface area on the primary substrate to prevent the cutting units from diving into the soft primary substrate. Substantially the entire length of the steel rule is supported by the secondary substrate, thereby yielding a rigid cutting unit that is not susceptible to deformation.
