    摘要： A lay-on roll (7) for co-operative engagement with a reel of pressure-sensitive sheet material carrying chemical residues during the reeling of said material, so as substantially to prevent the entrainment of air between the turns of said sheet material as they form on the reel, comprising a cylindrical support shell, a resilient base layer (31) of material carried by said support shell (30) and having a compressibility within a range to prevent said air entrainment at the reeling speed without damage to the sheet material, and a surface layer (32) substantially thinner than said base layer, of flexible material inert to said chemical residues.
