Abstract: The present invention relates to an apparatus and method for shaving the inside of barrels. In particular, the present invention relates to reconditioning used wine barrels by shaving the inside surface to a predetermined depth, ready for re-crozering, toasting, and re-use. Conventional shaving methods typically involve routing the internal surface by hand, but this technique is problematic in that it is a very slow process, the quality of the wood is often adversely affected, and there is no way of ensuring that the surface will be shaved to the same depth across the entire surface. Therefore, the resultant internal dimensions of the barrel are not reflective, relatively, of the original barrel surface. The apparatus of the present invention includes a scanning means adapted to scan the internal dimensions of the barrel, and a cutting means adapted to shave the internal surface to a predetermined depth relative to the scanned internal dimensions.

A saw carriage is mounted on the saw arm for reciprocal movement toward and away from a saw arm hinge axis. A single saw motor is mounted on the carriage and can be immobilized at selected angles. Separate horizontal-cut and vertical-cut saw blades are alternatively and interchangeably attached to the saw blade rotor.

Abstract: A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end.

Abstract: Apparatus for and a method of handling flexible tubes, for example in the production of a liner for a cargo container to provide a tubular attachment on the liner.

The support is then moved to the radial plane (FIG. 4) so as to stretch the tube 16 in the region of the support whereafter the tube is cut from the web, in the vicinity of the support. The support 39 is moved to a further processing station (FIG. 8), carrying the cut off tube 16, whereat the tube is released from the support 39 by tilting the support once more and withdrawing the support from the tube. The support is then returned to its initial position ready for another cycle of operation.

Abstract: An applicator wheel and guide system are provided in order to accurately align and position web material, either as discrete lengths or as a continuous strip, to articles or a continuous web. Specifically, the guide system includes a lateral edge guide disc rotatable with the applicator wheel which exhibits an edge guide surface at a first point along the periphery of the wheel applicator to precisely laterally align the web material and which moves radially inward from the surface of the applicator wheel at an application point so as not to obstruct the application of the web material to the articles or continuous web moved at a constant rate thereby. Moreover, the guide system includes the provision of an air bar for forming a loop in the supplied strip of web material prior to handling by the wheel applicator. The air bar eliminates roller inertia and guarantees consistent lengths of discrete lengths of web material to be applied to articles or a web when used on a wobbler arm.

Abstract: This disclosure describes a device for repeatably scribing a V-shaped scratch having sharply defined dimensions on the interior surface of a nuclear reactor fuel rod tube. A cutting tool having a V-shaped cutting tip is supported within the fuel rod tube so that the V-shaped cutting tip can be pivoted about an axis and scribe a scratch on the interior surface of the fuel rod tube. Lengthwise the scratch runs parallel to a line drawn through the axis of the fuel rod tube and is in the shape of an arc, and widthwise the scratch is V-shaped. This shape is used because the dimensions of the scratch can be plugged into appropriate formulas to calculate stress intensity of cracks in fuel rod tubes. Since the fuel rod tubes which are to be scribed may be radioactive, the scratching assembly is designed for use in a fixture which allows it to be operated in a cave by remote control handling devices.
