An apparatus for applying sealant to a seam in a container formed by overlapping portions of the sidewall, said apparatus including: conveying means operable for moving a container to and away from a first sealing station; first detecting means positioned adjacent to a portion of said conveying mean

An apparatus for applying sealant to a seam in a container formed by overlapping portions of the sidewall, said apparatus including: conveying means operable for moving a container to and away from a first sealing station; first detecting means positioned adjacent to a portion of said conveying means and being operable for detecting the rotational position of a container sidewall; first drive means positioned adjacent said first detecting means and being operable for selectively rotating a container to a predetermined rotational position; first sealant dispensing means positioned adjacent said conveying means at the first sealing station and being operable for dispensing sealant onto at least a portion of said seam, said first sealant dispensing means cooperating with means for providing relative movement between a portion of the first sealant dispensing means and the container, said sealant dispensing means including a nozzle; a support; a carriage; first means mounting the carriage on the support for reciprocal movement; power means operably connected to the carriage for selectively effecting reciprocal movement of the carriage; a hub; second means rotatably mounting the hub on the carriage; drive means operably connected to the second means operable for effecting rotation of the hub; at least one wiper secured to said hub, said wiper being of a resilient material and projecting outwardly from the hub and being adapted for wiping material from a nozzle during rotation of the hub by having a surface of the wiper engage the nozzle; and third means carried by the support and being operable for selectively engaging the surface of the wiper and removing from the surface of the wiper at least a portion of the material wiped from the nozzle. A method of applying sealant to a seam in a container formed by overlapping portions of a sidewall, said method comprising: moving a container to a first sealing station; detecting the rotational position of the container sidewall of the thus moved container; selectively rotating the container from the thus detected rotational position to a predetermined rotational position; moving a sealant applying nozzle from a first position to a second position relative to the container at the thus predetermined position and dispensing sealant onto at least a portion of said seam; moving the nozzle back to the first position; moving a surface of a wiper into engagement with an exterior surface of the nozzle adjacent a discharge opening of the nozzle when said nozzle is in said first position; moving the surface of the wiper relative to the exterior surface of the nozzle and transferring at least a portion of liquid on the nozzle to the surface of the wiper; and moving the surface of the wiper out of engagement with the exterior surface of the nozzle.
