Abstract: This invention provides methods and apparatuses for determining the non-true condition of a damaged metal wheel such as the wheel's radial runout, its lateral runout, and the length of its damaged zone. The invention provides for the use of components which rigidly hold the wheel in a fixture, which apply heat to the wheel in a controlled manner so as to raise the temperature of the wheel to its somewhat softened state, and which apply a suitable force to the damaged zone while the wheel is in its, or while it is being heated, to its somewhat softened state. This force is applied to the heated wheel until the radial runout of the damaged zone is reduced to a first predetermined limit. The invention also provides for the use of components which rotate the wheel between at least a pair of oppositely-positioned contacting and compressing rollers. This compression action occurs after the wheel has been heated to its, or while it is being heated to its, somewhat softened state.

Abstract: An apparatus for sealing and severing a web of film. The apparatus includes a first jaw located on one side of the web of film and a second jaw located on a second side of the web of film. The first and second jaws cooperate to grip the web of film. Located within the first jaw is a heater member for sealing and severing the web of film. The heater member is secured so that the time and/or pressure at which the heater member engages the web of film may be varied independent of the first jaw.

Abstract: A vertical form, fill, seal machine for continuously making filled three sided fin pouches is disclosed herein. Mechanisms for controlling the thermoplastsic web so that the seals are improved are disclosed. One of the mechanisms ensures that equal lengths of web are fed into the sealing jaws. The other mechanism that is carried by the jaws grasps and tensions the web immediately before and during the sealing of the web.

Abstract: An apparatus for attaching fitments a web of film. The apparatus includes an elongated tube, the web of film being passed around at least a portion of the elongated tube. A film puncher and remover for punching at least one hole in the web of film and removing the resultant slug is provided. The web of film passes between the elongated tube and the film puncher and remover. The apparatus also includes a fitment feed member for feeding a fitment from outside the elongated tube to a fitment pick-up position inside the elongated tube. The elongated tube also includes a fitment moving member for moving the fitment from the fitment pick-up position to a fitment attachment position. The fitment attachment position is located so that a portion of the fitment is received by the hole in the web of film. The apparatus also includes a sealer for welding the film to the fitment.

Abstract: An apparatus for sealing a web of film including a heater member for melting a portion of the film to create side and chevron seals. A back-up bar is located diametric the heater member. The heater member includes two elongated heater bars and two wing heater bars.
