Appeal No. 95-3922
Application No. 08/123,587
APPENDIX
Claim 23. An apparatus for joining ends of material webs to
each other to form a splice by an adhesive, comprising a
machine frame, at least two guide rollers (13, 14) rotatably
mounted to said machine frame in fixed positions symmetrically
relative to a plane of symmetry (2a) passing through a gap
(27) between said two guide rollers, two journal shafts (12)
mounted in said machine frame on opposite sides of said guide
rollers (13, 14) and on opposite sides of said plane of
symmetry (2a), two carriers (11) mounted on said journal
shafts (12) tiltable independent of each other, two web
holding and press-on heads (5, 6) each mounted to its
independently tiltable carrier, separate linear drives (10)
for separately stepping each of said holding and press-on
heads on its respective carrier (11) with linear stepwise
strokes crossing said plane of symmetry, said journal shafts
permitting tilting each of said carriers (11) and its holding
and press-on head into an out of the way position for access
to both holding and press-on heads (5, 6), said two journal
shafts (12) being arranged symmetrically relative to said
plane of symmetry (2a) and with a spacing from each other so
that in an operative nontilted position said holding and
press-on heads (5, 6) face each other directly across said
plane of symmetry (2a) with a minimal spacing between each
other sufficient for permitting a tilting movement and for
reducing said stepwise strokes to a minimum, a suction source
cooperating with said holding and press-on heads for holding a
web end in place, said linear drives (10) being adapted for
separately and linearly moving said holding and press-on heads
(5, 6) on its respective tiltable carrier (11) with different
forward and backward stepwise strokes crossing said plane of
symmetry (2a) toward each other for applying pressure to a
splice being formed and away from each other for moving said
holding and press-on heads (5, 6) out of contact with a web
for a web release, and, a cutting knife (16) comprising a
single blade (15) operatively mounted for operation in said
plane of symmetry (2a), each of said holding and press-on
