Systems and methods are provided for cleaning composite fabrication machinery. One embodiment is a method for cleaning of a composite application machine, comprising: displacing an anvil of a head of an Automated Fiber Placement (AFP) machine from an operation location relative to a cutter, cleaning at least one of the cutter and the anvil, and relocating the anvil to the operation location relative to the cutter.

A slicing machine may include a carriage that can be swiveled out with a supporting plate for supporting product to be sliced, wherein a locking device locks the supporting plate releasably in the slicing position. In order to make simple operation of the slicing machine possible accompanied by a high level of operating safety, the locking device has an electrically or electromagnetically operable actuator for releasing the carriage pivot bearing.

A processing liquid supplying apparatus including a reservoir containing an additive to be added to a liquid flowing through a passage connected at one end to a liquid supply source and at another end to a processing apparatus; an injection pump for injecting the additive into the passage; a weight measuring unit for measuring the weight of the reservoir and converting the weight into an electrical signal at a predetermined interval while the liquid flows in the passage and the additive is injected; a deciding unit for receiving the electrical signal from the weight measuring unit and deciding whether the measured value of the weight of the reservoir is being reduced at a predetermined rate; and a warning unit for issuing a warning that injection is improper when it is decided by the deciding unit that the measured value of the weight is not being reduced at the predetermined rate.

The sharpening system for cutter blades for cutting flexible materials in automatic cutting machines comprises at least one sharpening element, and it also comprises a first sharpening module that includes at least one first sharpening element, and a second sharpening module that includes at least one second sharpening element.

It provides a sharpening system that offers an integral and simple solution to current sharpening systems by incorporating an active sharpening system in the guide plate, either in the rotary area or on the outside, or symmetrically in the upper part of the lower body of the cutting head, interchangeably.

A cutting machine having a table with a working surface is disclosed. The working surface including a crossbeam above the working surface configured to be linearly positioned parallel to a first horizontal axis, a module, mounted on the crossbeam configure to be positioned parallel to a second horizontal axis, which extends perpendicularly to the first horizontal axis, a tool holder mounted in the module configured to move in a vertical axis and rotate about the vertical axis, and to accept one of a plurality of different interchangeable tools, and a control unit, wherein the tool holder has a connection device designed to supply the tool with power and a fluid, wherein the supply with the fluid is provided via a rotary joint, and wherein the power is provide via a rotary transmitter.

A method of cleaning a blade of a log saw of a converting line comprises applying a cleaning agent to a saw blade. The saw blade is adapted to cut a log of web material into rolls as the log of web material advances on a conveyor. In an another step of the method the log is advanced on the conveyor for cutting with the saw blade. In another step of the method, the saw blade is cleaned by cutting the log with the saw blade with the cleaning agent applied to the saw blade.

The present invention provides an entry sheet for drilling which provides higher hole position accuracy than that of a conventional entry sheet for drilling. The present invention provides an entry sheet for drilling, including a metal foil, and a layer including a resin composition and formed on at least one surface of the metal foil, wherein the resin composition includes a resin and tungsten disulfide as a solid lubricant, and the content of the tungsten disulfide included in the resin composition is 10 parts by mass to 200 parts by mass based on 100 parts by mass of the resin included in the resin composition.

A separating device for the chipless cutting to length of plastic workpieces, in particular plastic pipes, has a support part as support for the plastic workpiece and a blade which is movable relative to the support part. The separating device is configured to supply a wetting liquid to the blade at its contact point with the plastic workpiece to be machined. A method for the chipless cutting to length of a plastic workpiece uses a water-containing gel as an application lubricant for the contact points on the workpiece side during the chipless cutting to length of a plastic or plastic composite workpiece.

An ultrasonic cutting machine including a support structure, a positioning device moveable relative to the support structure, a cutting blade connected to the positioning device and a blade cleaning system positioned proximate the support structure, the blade cleaning system including a basin defining an internal volume and an opening into the internal volume, a solvent positioned in the internal volume, a cleaning surface positioned in the internal volume, wherein the cleaning surface is at least partially submerged in the solvent, and a lid positioned over the opening, wherein the lid is automatically displaced from the opening when the cutting blade approximates the basin.
