Abstract
In a machine for the manufacture of corrugated paper, apparatus is described for resiliently biasing the web guide means against the rolls of the corrugator as the corrugated web passes around the roll. In such apparatus a pair of spaced link bars are pivotally attached to a plate that is supported by the corrugator; the link bars also being pivotally connected to the guide means to provide a planar linkage. A ram attached to the plate and to one of the link bars resiliently urges the guide means toward the roll.
Claims3
Apparatus for resiliently urging the web guide means of a single facer station of a machine for making corrugated board toward the corrugating rolls so as to maintain the contact of the web of corrugated medium with the corrugating rolls, comprising:
- (a) plate means;
- (b) means for fixably supporting said plates on said machine;
- (c) a planar linkage connecting said guide means and said plates comprising
- (i) a pair of spaced bars,
- (ii) first pivot means connecting said bars and said plates, and
- (iii) second pivot means connecting said web guide and said bars whereby oscillation of said guide means is constrained within a predetermined plane,
- (d) pneumatic ram means;
- (e) a hanger connecting said ram and said plate;
- and
- (f) a pivot connecting said ram and one of said bars whereby said ram resiliently urges said guide means toward said roll to maintain the contact of said web with said corrugated roll.
