Abstract
A machine for rolling bulk material, such as fiber filters and tobacco, and wrapping a sheet member around the bulk material has a flexible apron connected to a roller bar which is rotated with an electric motor. The apron is located over a convex support between side walls having track slots for guiding the roller bar as it rolls up the apron and moves relative to the support. Bulk material placed on the apron adjacent the roller bar is rolled into a generally cylindrical shape within a sheet member as the apron moves over the support. The cylindrical product is discharged from the apron when the roller bar reaches the rear of the slots.
Claims20
A machine for rolling and wrapping bulk material with a sheet member comprising:
- a base,
- support means mounted on the base, said support means having side wall and an upward convex curved wall joined to said side walls, each of said side walls having an upwardly curved convex slot and a generally linear forward slot extended away from said convex curved support means, said curved slot having a rear and located adjacent the rear portion of the curved support means, roller bar means extends transversely of the convex curved wall, said bar means having opposite ends extended through said slots, a flexible apron draped over said convex curved support means, said apron having a first end attached to said bar means and a second end fixed with respect to said support means, and drive means for rotating said roller bar and moving the roller bar along said slots whereby bulk material placed on said apron adjacent said roller bar is rolled into a generally cylindrical shape within a sheet member carried by the apron and discharged as a cylindrical product from the apron when the roller bar means is moved to the rear of the slots.
A machine for rolling and wrapping bulk material with a sheet member comprising:
- a base, a cover mounted on said base surrounding a chamber, said cover having a front opening and a rear opening, support means located within said chamber extended between said front and rear openings, said support means having a convex curved wall providing a support surface, and side walls located adjacent opposite sides of said surface, each of said side walls having a convex curved slot and a generally linear slot extended away from said convex curved wall toward said front opening, roller means extended across said convex curved wall and into the slots in said side walls, flexible apron means secured to said roller means draped over the convex curved wall, said apron means being secured to said housing adjacent said rear opening in the housing, drive means including an electric motor mounted on a side wall below said convex curved wall, first gear drivably connected to the drive means rotatable upon operation of said motor, a second gear mounted on said roller means, said first gear being located in driving engagement with said second gear when the roller means is in the convex curved slots and out of engagement with said second gear when the roller means is in said linear slots, said rotation of the first gear causing the roller means to roll the apron means about the roller means and roll bulk material and a sheet member on said apron means adjacent said roller means into a cylindrical product and move the rolled apron means along said curved slots over said convex curved surface, said cylindrical product being discharged from the apron means adjacent the rear opening in said cover.
