Abstract
A reeling machine for winding a web, in particular a paper or cardboard web, for the formation of a wound web roll on a reel-spool, with a reeling drum, which forms a winding nip with the wound web roll and with at least one separating mechanism, which separates the web in a separating area. In the reeling machine, the separating mechanism is advanced before the separating process--as seen in vertical direction--from above to the separating area, which lies at a short distance to the outer periphery of the new reel-spool and/or--as seen in run direction of the web--to the winding nip between the reeling drum and the new reel-spool.
Claims26
Reeling machine for taking up a web, in particular a paper or cardboard web, for the formation of a wound web roll on a reel-spool, a reeling drum which forms a reeling nip with the wound web roll, at least one device which forms a free web loop between a new reel-spool and the wound web roll, and at least one separating mechanism for separating the web in a separation area, wherein the separation mechanism is movable from a first position spaced vertically above the separating area to a second position within the separation area, wherein when said separating mechanism is in said second position, the new reel-spool is pressed against the outer surface of the reeling drum with a predetermined force to form a reeling nip therewith, and wherein said separation area lies at one of a short distance from the outer periphery of the new reel-spool and at the reeling nip between the reeling drum and the new reel-spool and at a position along the free web loop.
A feeling machine for taking up a paper or cardboard web so as to form a wound web roll on a reel-spool, comprising:
- a reeling drum positioned so as to form a nip with the wound web roll;
- at least one device which forms a free web loop between a new reel-spool and the wound web roll;
- and
- at least one separating mechanism separating the web in a separation area;
- wherein the separating mechanism is movable to at least two positions, one position of the separating mechanism being spaced vertically above the separating area prior to a separating procedure, another position of the separating mechanism being within the separation area when the new reel-spool is pressed against the outer surface of the reeling drum with a predetermined force to form a reeling nip therewith, the separating area being spaced from an outer periphery of the new reel-spool by a predetermined distance and at a location along the free web loop formed between the new reel-spool and the wound web roll.
Process for reeling a web, especially paper or cardboard web, from a reel-spool onto a wound web roll, comprising:
- inserting an empty reel-spool from above into a separating area and pressing the new reel-spool against the outer surface of a reeling drum with a predetermined force to form a reeling nip therewith, the web being guided over the periphery of the reel-spool in some areas;
- forming at least one free web loop between the new reel-spool and the wound web roll;
- separating the web at a location along the free web loop, which is adjacent to the outer periphery of the new reel-spool in some areas, at one of (1) a short distance from the new reel-spool and (2) from the wound web roll between the reeling drum and the new reel-spool in the run direction of the web;
- and
- winding the loose end of the web onto the empty reel-spool.
A process for reeling a paper or cardboard web from a reel-spool onto a wound web roll, comprising:
- inserting an empty reel-spool from above and in a vertical direction into a separating area and pressing the reel-spool against the outer surface of the reeling drum with a predetermined force to form a reeling nip therewith and guiding the web over a periphery of the reel-spool;
- forming at least one free web loop between the new reel-spool and the wound web roll;
- separating the web at a location along the free web loop that is at least one of adjacent to the periphery of the reel-spool, near the reel-spool, and between the wound web roll and the reel-spool;
- and
- winding a loose end of the web on the reel-spool.
