Abstract
An apparatus including a trough having an upstream end, a downstream end and opposing sidewalls, an applicator roller carried by the trough, an adjustable scraper bar carried by the trough upstream of and adjacent to the applicator roller, an adjustment assembly for adjusting the scraper bar for allowing a user to adjust the amount of paste removed from the surface of the wallpaper, a lid removably and hingedly coupled to the trough for movement between an open position and a closed position, and an outfeed roller carried proximate the trough upstream of the scraper bar.
Claims23
A wallpaper paste applying apparatus for applying paste to a surface of wallpaper, said wallpaper paste applying apparatus comprising:
- a trough having an upstream end, a downstream end and opposing sidewalls;
- an applicator roller carried by said trough;
- a scraper bar adjustably carried by said trough upstream of and adjacent to said applicator roller, said scraper bar including an elongate member extending intermediate said opposing sidewalls of said trough and having a scraper portion located at a height proximate the back surface of the wallpaper to remove a predetermined amount of paste from the surface of the wallpaper, the scraper portion including an apex extending longitudinally along said elongate member, a beveled scraper surface contiguous with said apex and directed toward the surface of the wallpaper, said beveled scraper surface including a plurality of wales disposed therealong in spaced-apart relation and each separated by one of a plurality of valleys each having a predetermined depth, said apex and said plurality of wales to contact the surface of the wallpaper to remove paste therefrom to form a layer of paste upon the back surface of the wallpaper, and the layer defined by a plurality of ribs of paste corresponding to said plurality of valleys each separated by one of a plurality of grooves each formed by one of said plurality of wales;
- an adjustment assembly carried by said scraper bar for adjusting the height of said scraper portion for allowing a user to adjust the amount of paste removed from the surface of the wallpaper;
- a lid removably and hingedly coupled to said trough for movement between an open position and a closed position;
- and
- an outfeed roller carried proximate said trough upstream of said scraper bar.
A wallpaper paste applying apparatus for applying paste to a surface of wallpaper, said wallpaper paste applying apparatus comprising:
- a trough having an upstream end, a downstream end and opposing sidewalls;
- an applicator roller carried by said trough;
- a scraper bar adjustably carried by said trough upstream of and adjacent to said applicator roller, said scraper bar including an elongate member extending intermediate said opposing sidewalls of said trough and having a scraper portion located at a height proximate the back surface of the wallpaper to remove a predetermined amount of paste from the surface of the wallpaper, a first post rigidly carried by said elongate member and extending outwardly from a first end thereof, a second post rigidly carried by said elongate member and extending outwardly from a second end thereof, said first post rotatably and removably receivable by a groove of one of said opposing sidewalls and extending outwardly therefrom and terminating with an outer end at a point generally outboard of an outer surface of the one of said opposing sidewalls, said second post rotatably and removably receivable by another groove of the other of said opposing sidewalls and extending outwardly therefrom and terminating with an outer end at a position generally outboard of an outer surface of the other of said opposing sidewalls, means carried by said scraper bar for rigidly securing said elongate member to said trough;
- an adjustment assembly carried by said scraper bar for adjusting the height of said scraper portion for allowing a user to adjust the amount of paste removed from the surface of the wallpaper;
- a lid removably and hingedly coupled to said trough for movement between an open position and a closed position;
- and
- an outfeed roller carried proximate said trough upstream of said scraper bar.
A wallpaper paste applying apparatus for applying paste to a surface of wallpaper, said wallpaper paste applying apparatus comprising:
- a trough having an upstream end, a downstream end and opposing sidewalls;
- an applicator roller carried by said trough;
- a scraper bar adjustably carried by said trough upstream of and adjacent to said applicator roller, said scraper bar including an elongate member extending intermediate said opposing sidewalls of said trough and having a scraper portion located at a height proximate the back surface of the wallpaper to remove a predetermined amount of paste from the surface of the wallpaper;
- an adjustment assembly carried by said scraper bar for adjusting the height of said scraper portion for allowing a user to adjust the amount of paste removed from the surface of the wallpaper;
- a lid removably and hingedly coupled to said trough for movement between an open position and a closed position, the lid including a panel having a trailing edge pivotally and removably mounted proximate said downstream end of said trough and a leading edge, and a pair of engagement assemblies each carried proximate said leading edge of said panel of said lid and proximate said upstream end of said trough, each one of said pair of engagement assemblies for detachably engaging said leading edge of said panel to said trough proximate said upstream end;
- and
- an outfeed roller carried proximate said trough upstream of said scraper bar.
In combination with a wallpaper paste applying apparatus for applying paste to a surface of wallpaper of a type having a trough with an upstream end, a downstream end, opposing sidewalls and an applicator roller carried by the trough, a scraper bar carried by said trough upstream of said applicator roller to remove paste from the surface of the wallpaper, said scraper bar comprising:
- an elongate member extending intermediate the opposing sidewalls of the trough and having a scraper portion located at a height proximate the back surface of the wallpaper to remove a predetermined amount of paste from the surface of the wallpaper said scraper portion including an apex extending longitudinally along said elongate member, a beveled scraper surface contiguous with said apex and directed toward the surface of the wallpaper, said beveled scraper surface including a plurality of wales disposed therealong in spaced-apart relation and each separated by one of a plurality of valleys each having a predetermined depth, said apex and said plurality of wales to contact the surface of the wallpaper to remove paste therefrom to form a layer of paste upon the back surface of the wallpaper, the layer defined by a plurality of ribs of paste corresponding to said plurality of valleys each separated by one of a plurality of grooves each formed by one of said plurality of wales.
In combination with a wallpaper paste applying apparatus for applying paste to a surface of wallpaper of a type having a trough with an upstream end, a downstream end, opposing sidewalls and an applicator roller carried by the trough, an adjustable scraper bar assembly carried by said trough upstream of said applicator roller to remove paste from the surface of the wallpaper, said adjustable scraper bar assembly comprising:
- an elongate member extending intermediate the opposing sidewalls of the trough and having a scraper portion located at a height proximate the back surface of the wallpaper to remove a predetermined amount of paste from the surface of the wallpaper, the scraper portion including an apex extending longitudinally along said elongate member, a beveled scraper surface contiguous with said apex and directed toward the surface of the wallpaper, said beveled scraper surface including a plurality of wales disposed therealong in spaced-apart relation and each separated by one of a plurality of valleys each having a predetermined depth, said apex and said plurality of wales to contact the surface of the wallpaper to remove paste therefrom to form a layer of paste upon the back surface of the wallpaper, the layer defined by a plurality of ribs of paste corresponding to said plurality of valleys each separated by one of a plurality of grooves each formed by one of said plurality of wales;
