Paper sheets binding apparatus

Apparatus for binding a stack of perforated paper sheets utilizing flexible studs projecting from a first strip placed on one side of a marginal edge of the paper sheets stack wherein the studs pass through the sheet perforations and project through holes in a second strip placed on the opposite side of the marginal edge of the paper sheets stack comprising:

• a housing;
• means in said housing for supporting an assemblage of the strips and the paper sheets stack with the second strip being supported by said housing;
• clamping means for clamping the assemblage to said housing;
• and
• bending means for bending projecting ends of the studs to a position generally parallel to said second strip, said bending means comprising a first shuttle mounting a series of fixed bending blades having a cam surface contacting the projecting stud ends, lateral movement of said shuttle and said blades effecting the bending of the projecting stud ends.

Apparatus for binding a stack of perforated paper sheets utilizing flexible studs projecting from a first strip placed on one side of a marginal edge of the paper sheets stack wherein the studs pass through the sheet perforations and project through holes in a second strip placed on the opposite side of the marginal edge of the paper sheets stack comprising:

• a housing;
• means in said housing for supporting an assemblage of the strips and the paper sheets stack with the second strip being supported by said housing;
• clamping means for clamping the assemblage to said housing;
• and
• wherein said clamping means comprises a rotary pressure bar having a series of cantilevered fixed fingers extending therefrom, said fingers being rotatable with said pressure bar to contact the assemblage of strips and paper sheets stack.

A combined punch and binding apparatus having a housing;

• a hole punch mechanism in said housing and accessible to a stack of paper sheets insertable along a linear edge of the housing;
• a punch operational crank pivotally connected to said housing;
• means interconnecting said crank to said punch mechanism for operating said punch mechanism to punch a series of marginal apertures in a number of paper sheets;
• and
• a binding means extending from a side of said housing for binding a stack of punched paper sheets with a pair of plastic binding strips, one of said strips have a series of aligned apertures therein, the other of such strips including a series of flexible studs projecting therefrom, said studs being passed through the marginal apertures of a stack of sheets and through aligned apertures of said one strip ends of the studs projecting from the other strip being bendable into a groove in the one strip;
• and
• moveable bending means for bending the projecting stud ends, said bending means being interconnected to said operational crank such that up and down pivot movement of the crank moves said bending means laterally.

A binding apparatus comprising a housing:

• a first punch means in said housing for punching a first stack of paper sheets with marginal holes of a first size, spacing and shape;
• a second punch means in said housing for punching a second stack of paper sheets with marginal holes of a second size, spacing and shape;
• a punch operational pivot crank pivotally connected to said housing for operating said first and second punch means;
• a first binding station in said housing for binding the first stack of paper sheets including a first binding element including an element portion extending through the punched holes of the first stack of paper sheets;
• a second binding station in said housing for binding the second stack of paper sheets including a second binding element including an element portion extending through the punch holes of the second stack of paper sheets;
• and
• wherein at least one of said binding stations is interconnected to said pivot crank to effect binding of a selected one of the stacks by a selected one of the binding elements.

Apparatus for binding a stack of paper sheets including an apparatus housing;

• binding means in said housing for binding the stack of apertured paper sheets;
• and wherein said binding means comprises
• recess means for accepting a first binding strip having a series of holes generally corresponding in size and spacing to the apertures in a paper sheets stack placed thereon;
• means for accepting a second binding strip having flexible studs projecting therefrom of a size and spacing generally corresponding to the holes in the first binding strip, the studs passing through the apertures in the paper sheets stack and through the first binding strip holes, with ends of the studs projecting from the first binding strip;
• and
• bending means in said housing for bending the stud ends, said bending means comprising at at least one movable bending blade positioned below the first binding strip and being laterally movable to bend each projecting stud end into an underside stud-holding groove in said first binding strip;
• and
• means for moving said at least one bending blade under said recess means.
