Abstract:
A web spooling machine with automatic spool changing equipment in which an empty spool is placed against the web between the feed roller and the full spool. Pivoting arms carry a cutter blade which cooperates with a pivoting anvil or counterblade to sever the web. At the same time, an elastic guide engages the severed end of the web to guide it over the new spool while a pressure roller keeps it in place. The cutter blade is propelled into the path of the moving web by a torsional spring which is wound up by a cam follower whenever the mechanism returns to its starting position.
Abstract:
A surface winder for forming mill rolls of sheet material such as polystyrene foam sheet features a surface winder with an automatic web or sheet material transfer arrangement whereby a full mill roll is displaced and replaced by an empty core. The empty core automatically receives the severed end of the web and the winding operation continues on the empty core in an uninterrupted fashion.
Abstract:
There is described a device for longitudinally slitting a web and for separating the separated portions thereof before they are fed onto a takeup reel or core.
Abstract:
An automatic web taking-up device has a core disposed at one side of the travelling web for taking up the web, a press roller disposed oppositely to the core at the other side of the web, and a travelling cutter disposed in series with the press roller at the side where the web is fed into the nip between the input press roller for cutting the web.
Abstract:
Apparatus for transferring a continuous web of sheet material being wound onto a reel to a fresh core employs a rider roll to press the web as it is being wound and a guide roll for the web during transfer. Conveniently the reel and core are on a turnover stand and during transfer, when the reel is moved away from the rider roll, the guide roll is engaged with the web between rider roll and reel to avoid too long an unsupported run. It is also used to assist in wrapping the web around the new core and a web cutter is mounted in close association therewith. The sequence of movements of reel, core, rolls and cutter can be automatically controlled.
