The present disclosure relates to apparatus and methods for cutting a hollow turning vane to a desired length for use in a heating, ventilation, and air conditioning (HVAC) system. The vane cutting apparatus disclosed herein utilizes a pneumatically powered cutting mechanism that allows for a smaller apparatus footprint with no loss of cutting force and results in the single stepped blade rolling the inside edges of the hollow turning vane during cutting. The rolled inside edges provide a more secure and smoother fit when the hollow turning vane is fastened to the mating vane rail for use in an HVAC duct.

An apparatus for slicing food products includes a product feed and an interleaver. The product feed is operable to supply products to a cutting plane in a plurality of tracks running in parallel next to one another. At least one cutting blade is moved in the cutting plane. The interleaver has a conveying device for each track that is operable to convey a front end region of an interleaved sheet material web through the cutting plane in each track to provide the front end region in the respective track as an interleaved sheet between cut-off product layers. The interleaver is operable individually per track and each conveying device is configured such that it conveys the respective front end region of the respective interleaved sheet material web through the cutting plane individually per track in dependence on an angular position of the cutting blade.
