An apparatus for thermally attaching includes a thermally conductive support body (36; 86) with an edge surface (38; 88), a heater cartridge (42), a pneumatically expandable elastomeric element (44-54; 92-102), pinch plates (64, 66; 112, 114) for holding the elastomeric element in place, and passages (60, 62; 108, 110) for pressurizing the heated elastomeric element into contact with an element (24, 26) to be thermally attached to a mounting surface (85).

An improved light-tight package for a roll (10) of a length (14) light-sensitive material such as photographic film or paper includes an opaque leader (22) wound around the roll. Folded-over portions (48, 50) of opaque end disks (32, 34) are held in place by adhesive tape strips (44, 46). Upon unrolling one embodiment of the package by pulling the leader, the end disks release from the adhesive strips without tearing; and the adhesive strips remain attached to the leader and are removed from the roll with the leader. Upon unrolling another embodiment, the end disks tear circumferentially and the torn-away portions are removed with the tape strips and the leader.

A method of attaching film web 10 having a remaining portion 12 and a trailing end portion 18 to a spool 24 is disclosed. The method of attachment comprises forming a necked down portion 20 terminating in an axially extending flap 22 on trailing end portion 18 of film web 10. Moreover, the method of the invention comprises forming an adhesive member 34 comprising a central portion 36 for securely attaching to a seat 32 on elongated core 26 of spool 24, a first end portion 38 for securely attaching to one side of trailing end portion 18 of film web 10 such that first end portion 38 does not extend beyond necked down portion 20, and a second end portion 40 for securely attaching to the opposite side of said trailing end portion 18 beyond necked down portion 20 on non-image area 16 of film web 10. Additionally, the method of the invention is practiced by flexibly attaching adhesive member 34 to spool 24 and film web 10. the final step in the method of the invention is wrapping remaining portion 12 of film web 10 onto the edges of shoulders 28,30 of elongated core 26 so that remaining portion 12 of film web 10 overlies remaining portions 10 wrapped on shoulders 28,30 and trailing end portion 18 sandwiched between adhesive member 34 wraps onto seat 32 on elongated core 26 overlying adhesive member 34 wrapped onto seat 32.
