Machine for applying a uniform pressure

In a machine for applying pressure on a flat laminate material for adhesive securement to a relatively level surface, said machine comprising:

• (a) a portable weight bearing frame having a bottom portion,
• (b) a plurality of frame support rollers arranged in a spaced relation transversely of said frame for rolling engagement with said laminate material,
• (c) axle means for each roller having end portions protruded from opposite sides of the roller,
• (d) means for separately rotatably supporting each of said rollers including:
• (1) a pair of transversely spaced upright bracket means, each having an upright guideway with an adjacent upright surface, and a top end secured to said bottom portion of the frame,
• (2) a pair of bearing means for receiving the end portions of said axle means, each having a body portion guidably receivable in the guideway of an associated bracket means, said body portion including flange portions positioned between said associated bracket means and said roller and formed with fulcrum portions rideable on the adjacent surface of an associated bracket means to provide for pivotal movement of said bearing means with respect to said associated bracket means, and
• (3) yieldable pressure means that coact with said bracket means and said bearing means to oppose upward movement of said bearing means, and
• (e) said rollers disposed in at least two rows, with the rollers in one row arranged in a staggered relation relative to the rollers in the other row such that the rollers in one of said rows applies a pressure on the surface areas of the laminate material located between adjacent rollers of the other of said rows.

In a machine for uniformly applying pressure on a relatively level surface, said machine comprising:

• (a) a portable weight bearing frame,
• (b) at least one transversely extended frame supporting roller rotatably mounted from the bottom of said frame,
• (c) axle means for said roller having the ends thereof laterally projected from opposite sides of said roller, and
• (d) means for journaling said roller on said frame including:
• (1) a pair of transversely spaced upright bracket means, each having an upright guideway with an adjacent upright surface and a top end secured to the bottom of said frame;
• (2) a pair of bearing means corresponding to said bracket means for receiving the ends of said axle means, each bearing means having a body portion guidably movable in a guideway of an associated bracket means, and
• (3) coacting surface portions on the body portions of said bearing means and said bracket means for pivotal movement of said bearing means relative to said bracket means.
