Abstract

An edge roller assembly has a fixed guide member on which a support block is displaceable in a predetermined adjustment direction so as to move an edge roller rotatable on the block about an axis transverse to this direction. A threaded pin spindle extends generally parallel to the direction and bears on the block and is threaded into a nut in an adjustment member. A pair of links each have an inner end pivoted on the guide member and an outer end pivoted by means of a respective eccentric pin on the adjustment member. Thus rotation of these pins can relatively displace the adjustment and guide members, so as to move the rollers carried by the support blocks toward one another even while engaging a workpiece.

Dependent claims

An edge roller assembly comprising:

a fixed guide member;
a support block displaceable in a predetermined adjustment direction on said guide member;
an edge roller supported on said block and rotatable thereon about a roller axis transverse to said direction;
a threaded spindle centered on a spindle axis generally parallel to said direction and bearing in said direction on said block;
an adjustment member provided with a nut in which said spindle is threaded, whereby rotary pivoting of said spindle about said spindle axis relatively axially displaces said adjustment member and said roller;
at least one link having an inner link end and an outer link end, one of said link ends being pivoted about a link axis transverse to said direction on one of said members;
an eccentric pin having a cylindrical eccentric surface centered on an eccentric axis parallel to said link axis and pivoted on the other of said link ends and a cylindrical noneccentric surface centered on a noneccentric axis parallel to and offset from said eccentric axis and engaging the other of said members, said pin being rotatable about said noneccentric axis in said other member;
and
means including a drive motor and a worm-type stepdown transmission connected between said motor and said pin for rotating said pin about said noneccentric axis relative to said other member and thereby relatively displacing said guide member and roller in said direction.
