Abstract
Apparatus is provided for transporting a paper or film discrete object in a machine direction. A top engaging portion contacts a first side of the object and a bottom engaging portion contacts a second side of the object opposite the first side and respectively cooperates with the top engaging portion to grip and move the object in the machine direction. At least one of the top engaging portion or the bottom engaging portion includes a plurality of deflectable elements for engaging the object.
Claims25
An apparatus for transporting a paper or film discrete object in a machine direction, comprising:
- a top engaging portion for contacting a first side of the object;
- and
- a bottom engaging portion for contacting a second side of the object opposite the first side and respectively cooperating with said top engaging portion to move the object in the machine direction;
- wherein one of said top or bottom engaging portions includes a plurality of deflectable elements for engaging the object and the other of said top or bottom engaging portions includes a substantially solid surface for contacting the object.
An apparatus for transporting a pair of discrete side-by-side paper or film objects in a machine direction, comprising:
- a top engaging portion including a first pair of opposed belt assemblies for contacting respective first sides of each of the objects at respective lateral edges of each of the objects;
- and
- a bottom engaging portion including a second pair of opposed belt assemblies respectively cooperating with said first pair of belt assemblies for contacting second sides of each of the objects opposite the first sides and respectively cooperating with said top engaging portion to move the objects in the machine direction;
- wherein:
- one of said top engaging portion or said bottom engaging portion includes a plurality of bristles for engaging the objects;
- and
- said belt assemblies of at least said first pair or said second pair are non-parallel relative to one another.
An automatic envelope stuffing machine, comprising:
- a first end associated with feeding of a roll of paper in a machine direction;
- a portion configured to process the roll of paper into discrete paper objects;
- a second end associated with feeding of envelopes toward the discrete paper objects;
- and
- a transporting apparatus including a top engaging portion for contacting a first side of the objects and a bottom engaging portion for contacting a second side of the objects opposite the first side and respectively cooperating with said top engaging portion to move the objects toward the second end, wherein at least one of said top engaging portion or said bottom engaging portion includes a plurality of deflectable elements for engaging the objects.
A method of transporting a paper or film discrete object in a machine direction, comprising:
- contacting a first side of the object with a substantially solid surface;
- contacting a second side of the object opposite the first side with a substantially resilient surface deflectable upon engagement thereof with the object;
- and
- moving the substantially solid surface and the substantially resilient surface to thereby move the object in the machine direction.
