A fitment comprising a pouring spout having a peripheral flange at one end and a closure at a second end is attached to a paperboard carton formed with a hole in a side panel. The carton is moved intermittently along a conveyor, such as that used in a filling machine. An arm having a spud oscillates about a horizontal axis parallel to the conveyor. The arm is pivoted to down position as the carton reaches the fitment attaching station so that the fitment enters the open end of the carton with the spud aligned with the carton hole. The arm is mounted on a first carriage which reciprocates horizontally in a first direction to project the closure through the hole until the flange abuts the inside of the carton panel. An ultrasonic welding horn is mounted on a second carriage which reciprocates in alignment with the first carriage in a second direction opposite the first direction. The horn welds the fitment flange to the inside of the carton panel.

A method of attaching a fitment to a carton wherein said carton comprises a rectangular tube having walls and an open upper end, one said wall being formed with a hole and wherein said fitment comprises a spout smaller than said hole, and a peripheral flange at one end of said spout larger than said

A method of attaching a fitment to a carton wherein said carton comprises a rectangular tube having walls and an open upper end, one said wall being formed with a hole and wherein said fitment comprises a spout smaller than said hole, and a peripheral flange at one end of said spout larger than said hole, said method comprising the steps of moving said carton substantially horizontally parallel to a first substantially vertical plane to a fitment application position with said open end exposed, holding said carton stationary, moving a first carriage substantially parallel to a second substantially vertical plane, substantially perpendicular to said first vertical plane to a first carriage retracted position, oscillating an arm pivotally mounted on said first carriage substantially parallel to said second vertical plane, to a first arm position, said arm having a spud, applying a fitment to said spud while said arm is in first arm position adjacent said fitment application position, oscillating said arm substantially parallel to said second vertical plane to a second arm position with said spud and said fitment inside said carton and said fitment aligned with said hole, moving said first carriage substantially horizontally substantially parallel to said second vertical plane from said first carriage retracted position to a first carriage advance position and thereby moving said fitment laterally so that said spout protrudes out through said hole and said flange engages the inside of said one wall, moving a second carriage on which is mounted an annular welding head substantially horizontally substantially parallel to said second vertical plane from a second carriage retracted position to a second carriage projected position with said head engaging said one wall and surrounding said hole, said spout fitting inside said welding head, clamping said one wall and said flange between said welding head and said arm, and welding said flange to said one wall in weld.
