Abstract
A seaming assembly for placing seams in a continuously moving web of material. The seaming assembly includes a first support that is movable in a machine direction and a second support which is secured to the first support. The second support is movable relative to the first support in a cross direction. A seaming mechanism is mounted on the second support to place seams in the web that are at least partially in the cross direction. The first support may be movable in the machine direction at a speed that is substantially the same as the web such that the seaming mechanism places seams in the web that are substantially in the cross direction.
Claims22
A seaming assembly for placing seams in a continuously moving web of material, the seaming assembly comprising:
- a first support movable in a machine direction;
- a second support secured to said first support, said second support being movable relative to said first support in a cross direction;
- a seaming mechanism mounted on said second support to place seams in the web that are at least partially in said cross direction;
- and
- a cutting assembly that is secured to said second support such that said cutting assembly is movable with the first support in the machine direction and movable relative to said first support in the cross direction.
A seaming assembly for placing seams in a continuously moving web of material, the seaming assembly comprising:
- a first support movable in a machine direction;
- a second support secured to said first support, said second support being movable relative to said first support in a cross direction;
- a seaming mechanism mounted on said second support, said seaming mechanism including a stitching assembly that sews stitches in the web which are at least partially in said cross direction;
- a cutting assembly that is secured to said second support such that said cutting assembly is movable with the first support in the machine direction and movable relative to said first support in the cross direction, said cutting assembly configured to cut the web into sections;
- and
- a controller that monitors and adjusts the speed of at least one of the web and said first support.
A method of placing seams in a moving web, the method comprising:
- feeding the web into a seaming assembly;
- moving a first support in the seaming assembly in a machine direction;
- moving a second support that is secured to the first support relative to the first support in a cross direction, the first support being moved at a speed that is substantially the same as the speed of the web for the entire duration of movement of the second support across the web in the cross direction;
- and
- placing seams in the web that are substantially in said cross direction using a seaming mechanism that is mounted on the second support of the seaming assembly.
