Abstract
A system and method for performing a splicing operation where the splicing apparatus is configured to orient the web to ensure the two sealing sides are presented to each other and the splice is always made on one side of the web.
Claims12
A splicing apparatus comprising:
- a lower roll drawer configured to hold a lower web material in alignment with a first predefined location;
- a first cylinder actuated to cause an upper web material to be engaged by a first clamp, the first cylinder also configured to cause the upper web material to engage a cutting edge to separate the upper web material into a downstream upper web portion and an upper web portion;
- a second cylinder actuated to cause the downstream upper web portion to be engaged by a second clamp;
- first cylinder actuating to return it to an initial position;
- a third cylinder configured to cause the downstream upper web portion to be placed in alignment with the first predefined location;
- and
- a fourth cylinder configured to cause a first side of the downstream upper web material to be in contact with a first side of the lower web material at the first predefined location.

A method comprising the steps of:
- securing, using a lower roll drawer, a lower web material in alignment with a first predefined location;
- clamping, using a first set of one or more clamps, an upper web material;
- separating the upper web material to into a downstream upper web portion and an upper web portion via a first cylinder;
- clamping, the downstream upper web portion, wherein a second cylinder causes the downstream upper web portion to be clamped by a second set of one or more clamps;
- causing, using a third cylinder, the clamped downstream upper web portion to be extended so that a first side of the downstream upper web portion is in alignment at the first predefined location;
- and
- compressing, using a fourth cylinder, the first side of the downstream upper web portion with a first side of the lower web material at the first predefined location.
