<p>The machine is particularly for paper strip (PB), having two rollers (TW1,TW2) supporting the coil to be formed (R). The casings (M1,M2) of the rollers distort, preferably to different degrees. During the coiling operation, the strip passes through the gap (G) between the rollers and part-way round one of them. The chamber (DR) between the rollers and the partly-farmed coil is sealed at the ends and underside and supplied with compressed air to relieve the weight of the coil. The seal below the gap has a sidewall (11) extending for the maximum overall width of the coil to be formed, and hinging on an axis (11A) parallel to those of the rollers. It swings between a position forming a seal against the roller round which the strip passes, while leaving a gap (GP) through which the strip passes during coiling, and one clear of the roller to allow the strip to be threaded into place. The gap (GP) an be extended by guide faces clear of the roller in the radial direction and towards the incoming strip.</p> |
