Abstract
A trough having an upstream end and a downstream end removably carrying an applicator roller rotated by driving means and a scraper bar, the scraper bar upstream of and adjacent the applicator roller, and a pressure area downstream of the applicator roller. A lid hingedly coupled to the trough, carrying an outfeed roller downstream of the scraper bar for guiding wallpaper over the applicator roller and the scraper bar.
Claims16
A wallpaper paste applying apparatus for applying paste to a back surface of wallpaper comprising;
- a trough having an upstream end and a downstream end;
- an applicator roller removably carried by said trough;
- an adjustable scraper bar removably carried by said trough upstream of and adjacent to said application roller, said adjustable scraper bar including an elongate member extending between opposing sidewalls of said trough, said elongate member having a scraper portion with a hook shaped cross-section, said scraper portion having an apex extending longitudinally therealong positioned in an upward direction to contact said wallpaper, and a plurality of notches having an adjustable depth formed along said apex, said notches having an upstream edge, and a depth being the vertical distance between said apex and said upstream edge said depth adjustable by tilting said elongate member, thereby positioning said upstream edge to remove a predetermined level of paste from said wallpaper;
- drive means for driving said applicator roller;
- a lid removably and hingedly coupled to said trough for movement between an open position and a closed position;
- and
- an outfeed roller carried by said lid, positioned upstream of said adjustable scraper bar in the closed position.
A wallpaper paste applying apparatus for applying paste to a back surface of wall paper comprising:
- a trough having an upstream end, a downstream end, a bottom having a portion sloping downward from said upstream end to a substantially horizontal portion, opposing sidewalls extending upward from said bottom, an upstream endwall extending upward from said bottom at said upstream end, and a downstream endwall extending upward from said bottom at said downstream end;
- an applicator roller removably carried by said trough, positioned adjacent said bottom proximate said downstream end;
- and
- a pressure area downstream of said applicator roller, for receiving build-up of paste during operation, said build-up closing voids formed between said applicator roller and said paste, and contacting said applicator roller, said pressure area is defined by said applicator roller and said downstream endwall, said downstream endwall constructed to closely follow the curve of said applicator roller and having an uppermost portion with an edge angled inward parallel to said applicator roller so as to form a space therebetween.
A wallpaper paste applying apparatus for applying paste to a back surface of wallpaper comprising:
- a trough having an upstream end and a downstream end;
- an applicator roller removably carried by said trough;
- and
- a scraper bar carried by said trough upstream of said applicator roller, said scraper bar including an elongate member extending between opposing sidewalls of said trough, said elongate member having a scraper portion with a hook shaped cross-section, said scraper portion having an apex extending longitudinally therealong positioned in an upward direction to contact said wallpaper, and a plurality of notches having an adjustable depth formed along said apex, said notches having an upstream edge, and a depth being the vertical distance between said apex and said upstream edge said depth adjustable by tilting said elongate member, thereby positioning said upstream edge to remove a predetermined level of paste from said wallpaper.
