Abstract
Abstract This apparatus provides a continuous form with a series of precut, longitudinally spaced record cards adhered thereto so as to be movable by conventional forms tractors through a high-speed printer. The cards have detachable marginal stub portions that are glued to the form by a heat-settable glue. After glue is applied to the form, the cards are fed onto the form. The card/form assemblage is then advanced through an elongated nip between two sets of opposing endless belts, at least one of the belts of each set being heated, to subject the assemblage to heat and pressure for a period of time proportional to the length of the nip and speed of the belts to set and dry the glue so as reliably to seal the cards to the form. Application of the glue to the form and of the cards to the glue is performed while the form and cards are in continuous motion, providing a high throughput.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
256 words
Apparatus for joining a plurality of substantially similar discrete record cards successively at substantially equal distances to and along a manifold continuous form, said cards and form being of the type having similarly spaced alignable line hole perforations adjacent both longitudinal edges, said apparatus comprising: means for moving the form continuously at substantially constant speed along a predetermined path: means for applying adhesive in a discontinuous preselected pattern to the form as it advances; means for thereafter advancing the cards sequentially onto the form at a speed substantially equal to that of the form; and sealing means for applying heat to at least one side of the assemblage defined by the moving form and overlying cards and concurrently applying pressure to the assemblage to set and dry the adhesive to adhere the cards to the form while both are continuously moving, said sealing means including: a first set of members engaging one side of the assemblage longitudinally along the adhesive pattern; another set of members engaging the other side of the assemblage to pinch the assemblage between it and said first set for a preselected time interval proportional to the length of the nip defined between said sets; and at least one of said sets of members being of heat-conductive material to transmit heat as well as apply pressure to said assemblage, and at least one of said sets of said members moving continuously in an elongated endless path and including belts with drive pins that protrude through the aligned perforations in the form and cards.
Claim 2
Dependent Claim
256 words
Apparatus for joining a plurality of substantially similar discrete record cards successively at substantially equal distances to and along a manifold continuous form, said cards and form being of the type having similarly spaced alignable line hole perforations adjacent both longitudinal edges, said apparatus comprising: means for moving the form continuously at substantially constant speed along a predetermined path: means for applying adhesive in a discontinuous preselected pattern to the form as it advances; means for thereafter advancing the cards sequentially onto the form at a speed substantially equal to that of the form; and sealing means for applying heat to at least one side of the assemblage defined by the moving form and overlying cards and concurrently applying pressure to the assemblage to set and dry the adhesive to adhere the cards to the form while both are continuously moving, said sealing means including: a first set of members engaging one side of the assemblage longitudinally along the adhesive pattern; another set of members engaging the other side of the assemblage to pinch the assemblage between it and said first set for a preselected time interval proportional to the length of the nip defined between said sets; and at least one of said sets of members being of heat-conductive material to transmit heat as well as apply pressure to said assemblage, and at least one of said sets of said members moving continuously in an elongated endless path and including belts with drive pins that protrude through the aligned perforations in the form and cards.
Claim 3
Dependent Claim
41 words
Apparatus according to claim 1, including: means for mounting the respective sets of members; and means for adjusting the spacing between the respective sets of members to thereby adjust the degree of pressure exerted on the assemblage while within the nip.
Claim 4
Dependent Claim
74 words
Apparatus according to claim 1, wherein said sealing means comprises: a shoe providing a substantially flat surface; means for heating said surface; at least one elongated endless belt of heat-conductive metal entrained past said surface and around said shoe; and a series of idler rolls rotatably supported by said shoe for maintaining the belt spaced with minimal clearance from the surface to minimize friction while permitting heat transfer from the surface to the belt.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 1, wherein said means for moving the form continuously along said path includes endless means having tractor pins that engage and drive the belts by which the form and cards are driven.
Claim 6
Dependent Claim
57 words
Apparatus according to claim 1, wherein: the adhesive is a glue which is wet at the time the cards are advanced onto the form; and wherein the adhesive-applying means is of the gravure type and applies the glue in a selected pattern corresponding to the preselected length of the cards and spacing between them on the form.
Claim 7
Dependent Claim
86 words
Apparatus according to claim 1, wherein said sealing means comprise: a pair of shoes providing substantially parallel facing surfaces; means for heating at least one of said surfaces; at least one set of juxtaposed elongated endless belts, those of each set passing around a respective one of the shoes and with very slight clearance over and along said surfaces; means for spacing the belts from said surfaces to provide said slight clearance to minimize friction; and means for heating at least one belt of each set.
Claim 8
Dependent Claim
209 words
Apparatus for joining a plurality of substantially similar discrete record cards sequentially on a continuous form, which web and cards have similarly spaced alignable line hole perforations adjacent opposite longitudinal edges, comprising: means for moving the form continuously at substantially constant speed along a predetermined path; gravure means for applying a heat-settable glue in a discrete gravure pattern at preselected longitudinal intervals on the moving form; means for thereafter advancing the cards sequentially onto the form at a speed substantially equal to that of the form; said means for moving the form including juxtaposed endless means providing an elongated nip into which the assemblage defined between moving form and overlying cards is advanced, one of said juxtaposed means including drive pins that protrude through the aligned perforations in the form and cards; at least one of said juxtaposed means being of a heat-conductive material; heating means for heating the heat-conductive material; and such that heat is applied to at least one side of the assemblage while it is concurrently being subjected to fusing pressure for a period of time proportional to the length of the nip so as to set and dry the glue to effect adhesion of the cards to the form while both are in continuous motion.
