Abstract
An apparatus for ventilating a web of material used in the manufacture of pocketed springs may be removably attached to a pocket coiler. The apparatus has an upper movable portion which pivots relative to a stationary portion. The stationary portion may be removably attached to the pocket coiler. Each portion has at least one roller, a web of material passing between the rollers during use. One of the rollers may have protrusions to create openings in the material before the material enters the pocket coiler.
Claims18
An apparatus for creating ventilation openings in fabric used to create a continuous string of pocketed springs, said apparatus comprising:
- a stationary portion and a movable portion, the stationary portion comprising a stationary frame having two sides;
- a brush roller shaft extending between the stationary frame sides;
- at least one brush roller mounted on the brush roller shaft;
- guide rollers extending between the sides of the stationary frame;
- the movable portion of the apparatus comprising two opposed frame members joined together by at least one support member;
- a pin roller shaft extending between the frame members of the movable portion of the apparatus;
- at least one pin roller mounted on the pin roller shaft;
- a drive assembly in the moveable portion of the apparatus, the drive assembly comprising a motor for rotating a drive sprocket for rotating a chain for rotating a driven sprocket, which rotates the pin roller shaft and the at least one pin roller mounted on the pin roller shaft,
- wherein each of the opposed frame members of the movable portion of the apparatus is pivotally secured to one of the sides of the stationary portion of the apparatus.
An apparatus for creating ventilation openings in fabric used to create a continuous string of pocketed springs, said apparatus comprising:
- a stationary portion mounted to a pocketed coiler;
- a movable portion pivotally mounted to the stationary portion of the apparatus;
- the stationary portion of the apparatus comprising a stationary frame having an opening;
- a brush roller shaft extending between opposed sides of the stationary frame;
- a brush roller mounted on the brush roller shaft and extending at least partially through the opening;
- guide rollers extending between the stationary frame members;
- the movable portion of the apparatus comprising two opposed frame members joined by at least one support member;
- a pin roller shaft extending between the opposed frame members of the movable portion of the apparatus;
- at least one pin roller mounted on the pin roller shaft;
- and
- a drive assembly including a motor for rotating the pin roller shaft and the at least one pin roller mounted on the pin roller shaft,
- wherein the two opposed frame members of the movable portion of the apparatus are pivotally secured to the stationary portion of the apparatus.
