Abstract

A multi-purpose laminating and adhesive transfer apparatus having a frame supporting rotatably engaging nip rollers. The frame and has upper and lower feed rolls which may be a laminate, film or paper, or an adhesively coated film or a film having an affinity for adhesive. The upper and lower feed rolls containing the webs of laminating or adhesive transfer material have tensioning caps which can be adjusted to provide the proper tensioning to prevent the rollers from overrunning as they rotate. The tensioning caps are pre-set and provided to the user. A cutter blade is positioned at the discharge side of the nip rollers and may be actuated to sever the master at any desired location. The apparatus may be operated to apply lamination to either top or bottom surfaces of a substrate.

Claims18

Dependent claims

An applicator and transfer device comprising:

(a) a frame having opposite sides;
(b) a first nip roller rotatably mounted and extending between said sides of said frame;
(c) a first mounting means for mounting a feed roll to said frame;
(d) second nip roller rotatively mounted and extending between said sides of said frame adjacent said first nip roller;
(e) second mounting means for mounting a feed roll to said frame;
(f) actuating means for imparting rotation to at least one of said nip rollers;
(g) first and second feed rolls of material each having a generally cylindrical core about which feed material is wound and being supported for rotation in said respective first and second mounting means;
and
(h) pre-tensioning means associated with each of said cores for selectively establishing a predetermined resistance to rotation of the rolls of material to provide the proper application tension for unwinding the feed material wherein said pre-tensioning means includes a tensioning cap affixed to said cores, said caps having an end plate engaging the end of the associated core and said plate with securement means engageable in said mounting means and further including biasing means for applying a predetermined force biasing said end plate into engagement with the end of said roll core.

An applicator and adhesive transfer device comprising:

(a) an upper frame member having opposite sides and a lower frame member having opposite sides, said upper frame member being pivotally connected to said lower frame member;
(b) a first nip roller rotatively mounted and extending between the sides of said upper frame member:
(c) first mounting means associated with the upper frame member;
(d) a second nip roller rotatively mounted and extending between the sides of said lower frame member;
(e) second mounting means associated with the said lower frame member;
(f) first and second rolls of feed material each having a generally cylindrical core about which the feed material is wound and being supported for rotation in said respective first and second mounting means;
(g) pre-tensioning means integrally associated with each of said cores for selectively establishing a predetermined resistance to rotation of the rolls of feed material to provide the proper application tension for the feed material, said pre-tensioning means including a tensioning cap affixed to said associated core having an end plate engaging the associated core and said plate having with securement means engageable in said mounting means and further including biasing means for applying a predetermined force biasing said end plate into engagement with the associated core;
and
(h) actuating means for imparting rotation to at least one of said nip rollers.
