Abstract: High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.

Abstract: A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet.Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings.

Abstract: A web of unvulcanized rubber or other curable material moves intermittently in generally horizontal passes through several superposed stages of a multiplaten press by way of a pair of stretching stations flanking the press, each stretching station including a clamp and, with three or more curing stages, at least one deflection roller for the web. Each clamp has at least two jaws which are closable around one or more web passes and, together with the associated deflection roller or rollers, initially hold these passes substantially on the level of the midplanes of the spaces between the open press platens. From this position the jaws and rollers are jointly displaceable in a vertical direction (e.g. downwardly), after a stretching of the web by an outward movement of the clamps and/or the rollers, into a position in which the several passes come to rest simultaneously on the heated platens between movable spacing strips. The platens thereupon successively close in the opposite vertical direction (e.g.
