Abstract
A paint arrestor for absorbing paint overspray comprises a series of layers of sheet material, each of the layers being slit and expanded to define an array of air spaces distributed in columns. The air spaces alternate in size from column to column and repeat in size in every other column. Means are provided for securing the layers in contiguous, overlying relationship with one another.
Claims14
A paint arrestor for absorbing paint overspray comprising:
- a series of layers of sheet material, each of said layers being slit and expanded to define an array of air spaces distributed in columns, said air spaces alternating in size from column to column and repeating in size in every other column;
- and
- means for securing said layers in contiguous, overlying relationship with one another.
A paint arrestor for absorbing paint overspray comprising:
- a series of layers of sheet material, each of said layers being slit and expanded to define an array of generally hexagonally-shaped air spaces distributed in columns, said air spaces alternating in size between a first predetermined size and a second predetermined size smaller than said first predetermined size and repeating in size in every other column;
- and
- means for securing said layers in contiguous, overlying relationship with one another, wherein each of said layers defines an intersecting grid pattern having first runners intersecting with first baffles to define each of said air spaces of said first predetermined size and having said first runners intersecting with second baffles to define each of said air spaces of said second predetermined size, said first baffles being formed with elongated slits therein and said first baffles and said second baffles are oriented at a positive slope with respect to the plane of one said layers of sheet material and said first and said second baffles are oriented at a negative slope with respect to the plane of an adjacent one of said layers of sheet material.
A paint arrestor for absorbing paint overspray comprising:
- a series of layers of expandable sheet material, each of said layers, when unexpanded, having an array of slits formed therein and distributed in columns, said slits varying in size between a first predetermined size, a second predetermined size smaller than said first predetermined size and a third predetermined size smaller than said second predetermined size, said slits of said first and second predetermined sizes alternate within a given column and said slits of said third predetermined size are horizontally aligned with said slits of said second predetermined size and distributed in said columns on either side of said slits of said first and second predetermined sizes;
- and
- means for securing said layers in contiguous, overlying relationship with one another.
