Abstract
An apparatus and method for removing cutout material that is at least partially severed from a web has a vacuum passage for drawing a vacuum, and a vacuum inlet plate connected to the vacuum passage. The vacuum inlet plate has an inlet edge defining at least part of an opening into the vacuum passage. The inlet edge has first and second angled edge portions that converge at first and second angles relative to the machine direction, respectively, to meet at a vertex portion. The vertex portion constitutes the rearmost portion of the inlet edge relative to the machine direction.
Claims31
An apparatus for removing cutout material that is at least partially severed from a web moving in a machine direction, the apparatus comprising:
- a vacuum passage for drawing a vacuum;
- a vacuum inlet plate connected to the vacuum passage, the vacuum inlet plate comprising an inlet edge defining at least part of an opening into the vacuum passage;
- and
- wherein the inlet edge comprises first and second angled edge portions converging at first and second angles relative to the machine direction, respectively, to meet at a vertex portion, the vertex portion comprising the rearmost portion of the inlet edge relative to the machine direction.
An apparatus for removing cutout material that is at least partially severed from a fabric web moving in a machine direction, the apparatus comprising:
- a vacuum passage for conveying a vacuum;
- an inlet, connected to the vacuum passage, having an inner face facing the vacuum passage, an outer face opposite the inner face, a trailing edge located in a furthest position relative to the machine direction, and a leading edge opposite the trailing edge;
- the inlet having an inlet edge defining an opening that allows the passage of the cutout material into the vacuum passage;
- the inlet edge comprising a first angled edge portion and a second angled edge portion, the first angled edge portion oriented at a first angle relative to the machine direction, and the second angled edge portion oriented at a second angle relative to the machine direction;
- the first angled edge portion and the second angled edge portion converging at a vertex portion;
- the inlet edge being oriented such that the vertex portion is at the rearmost point of the inlet edge along the machine direction.
