Document Type and Number:
Japanese Patent JP2739575
Kind Code:
B2
Abstract:
An apparatus is disclosed for assisting the transfer of a web (Wb) disposed contiguous relative to a transfer felt (40b) such that the web is transferred from a lead-in roll (38b) disposed adjacent to a press section (12b) to a first dryer (42b) of a papermaking machine dryer section (14b). The apparatus (10b) includes an intermediate support roll (52) disposed between the lead-in roll (38b) and the first dryer (42b) such that the transfer felt (40b) is disposed between the web (Wb) and the intermediate roll (52). A first transfer box (54) is disposed between the lead-in roll (38b) and the intermediate roll (52) such that the transfer felt (40b) is disposed between the web (Wb) and the first transfer box (54). The first transfer box (54) is oriented relative to the transfer felt (40b) such that a partial vacuum is generated between the first box (54) and the transfer felt (40b) for drawing the web (Wb) into close conformity with the transfer felt (40b) between the lead-in roll (38b) and the intermediate roll (52). A second transfer box (56) is disposed between the intermediate roll (52) and the first dryer (42b) such that the transfer felt (40b) is disposed between the web (Wb) and the second box (56). The second box (56) is oriented relative to the transfer felt (40b) such that a partial vacuum is generated between the transfer felt (40b) and the second box (56) for drawing the web (Wb) into close conformity with the transfer felt (40b) between the intermediate roll (52) and the first dryer (42b) such that any tendency of the web (Wb) to droop relative to the transfer felt (40b) between the lead-in roll (38b) and the first dryer (42b) is inhibited.
