Buttonless conveyor belt
A conveyor belt is made with a series of spaced apart buttonless rods. The buttonless rods are connected to each other with a plurality of links. The buttonless ends of the rods are welded or otherwise affixed to the links so that the ends of the rods are substantially coplanar with the outer surface of the links. This forms a relatively smooth link surface, which is readily cleaned and sanitized. Additionally, wear and tear is reduced on driving grip surfaces that frictionally grab onto the links.
1. A method for making a conveyor belt comprising the steps of:
(i) providing a rod on a manufacturing surface;
(ii) providing a first link configured to receive a first end of the rod on a first side of the manufacturing surface;
(iii) providing a second link configured to receive a second end of the rod on a second side of the manufacturing surface, the second link being spaced apart from the first link approximately a length of the rod;
(iv) offsetting the first link and the second link in a manufacturing direction;
(v) aligning the first end of the rod with the first link;
(vi) inserting the first end of the rod through the first link far enough to provide clearance between a second end of the rod and the second link;
(vii) aligning the rod with the second link by advancing the rod in the manufacturing direction;
(viii) inserting the second end of the first elongated rod through the second link so that the first end of the rod is substantially coplanar with an outer surface of the first link; and
(ix) welding the first end of the rod to the outer surface of the first link so that a first weld covers the first end of the rod and a first weld outer surface is flush with the outer surface of the first link.
2. The method of claim 1 , wherein step (viii) entails positioning the first rod end flush with the outer surface of the first link.
3. The method of claim 1 , wherein step (vi) entails driving the rod through the first link with a first piston and step (vii) entails driving the rod through the second link with a second piston.
4. The method of claim 3 , at least one of the first piston and the second piston being pneumatic.
5. The method of claim 1 , further comprising the step of
(x) positioning the rod so that the second end of the rod is substantially coplanar with an outer surface of the second link prior to welding the first end of the rod.
