<p>A device for pleating unfilled tubular casings, such as sausage skins, so that a knot can be tied round the pleated end, has a pair of parallel plates (30,31) with a small separation to allow the casing, in the form of a web, to pass between them on its way to a knotting and cutting station. Folding and guiding elements, which may be in the form of vertical rollers (35) and transverse elements or rollers (36,37), are arranged on the plates and narrow towards the exit of the device so that the edges of the web are repeatedly folded over themselves, resulting in the desired pleats.</p> |
