Abstract
Nel comando del filo per macchine tessili che realizzano maglie con consumo del filo non costante, ad esempio nel caso delle macchine rettilinee per maglieria, vengono impiegati mezzi di richiamo del filo che presentano ciascuno un braccio orientabile. Nel caso di una macchina rettilinea per maglieria, questi mezzi di richiamo del filo compensano le variazioni di sollecitazione del filo che si manifestano all'atto della inversione del movimento della slitta. A monte dei mezzi di richiamo del filo lungo il percorso di spostamento del filo è collegato un freno del filo con possibilità di comando, mentre il braccio orientabile dei mezzi di richiamo del filo è collegato con un generatore di momento torcente elettromeccanico. Il freno del filo e il generatore del momento torcente del braccio orientabile dei mezzi di richiamo del filo vengono comandati all'atto della inversione della slitta in modo tale per cui la sollecitazione del filo viene mantenuta pressoché costante, di guisa che si ricava anche nelle zone dei bordi del prodotto tessuto a maglia una formazione uniforme della maglia. Nel corso della stessa formazione della maglia la sollecitazione del filo viene mantenuta costante dal dispositivo di regolazione il quale presenta una unità di misura della sollecitazione del filo.In the control of the thread for textile machines that make knits with variable thread consumption, for example in the case of straight knitting machines, yarn return means are used which each have an adjustable arm. In the case of a rectilinear knitting machine, these yarn return means compensate for the variations in stress of the yarn which occur when the movement of the slide is reversed. A wire brake with control option is connected upstream of the wire return means along the wire movement path, while the swivel arm of the wire return means is connected with an electromechanical torque generator. The wire brake and the torque generator of the swiveling arm of the wire return means are controlled when the slide is reversed so that the wire stress is kept almost constant, in a manner that is also obtained in the areas of the edges of the knitted fabric product a uniform formation of the mesh. During the same formation of the mesh, the stress of the thread is kept constant by the adjustment device which has a unit for measuring the stress of the thread.
