Abstract
A belt cradle cloth roll support apparatus for a cloth spreading machine including a pair of first and second endless belt members defining a V-shaped trough and trained about a plurality of rollers, including an adjustment mechanism for moving one of the belt members toward and away from the other belt member in order to decrease the angle of the V-shaped trough in order to better contain and control smaller diameter cloth rolls which have diminished in size as they are unwound while supported on the V-shaped belt cradle.
Claims7
In a cloth spreading machine including a longitudinally movable machine frame, a cloth feed and support apparatus comprising:
- (a) a cloth roll support frame having a longitudinal feed axis and opposite first and second ends,
- (b) a roll support cradle mounted in said roll support frame,
- (c) said cradle comprising first and second endless belt means extending longitudinally in a feed direction, said first and second belt means defining a substantially V-shaped trough and having lower adjacent end portions, said cradle being adapted to support a cloth roll extending transversely of said support frame and bearing on both said first and second belt feed means in an operative position,
- (d) first transverse roller means supporting said first belt means for rotary movement,
- (e) said first transverse roller means comprises upper and lower belt rollers having corresponding rotary axes, about which said first endless belt means is trained,
- (f) second transverse roller means supporting said second belt means for rotary movement,
- (g) means for driving at least one of said roller means for moving said belt means in said feeding direction, and
- (h) adjustment means cooperating with said cradle for positively moving said lower portion of one of said belt means toward and away from the lower portion of said other belt means in order to vary the angle of said V-shaped trough, and
- (i) said adjustment means further comprises a transverse intermediate roller between said upper and lower belt rollers and within said first endless belt means, and means for moving said intermediate roller toward and away from the common plane containing the rotary axes of said upper and lower rollers.
