Abstract
Abstract A detecting mechanism in a film magazine spooling machine for detecting a missing or displaced film end portion of a film magazine. The detecting mechanism comprises a sensing mechanism movable to a position for sensing the edge of an accurately positioned web end portion. If such web end portion is missing or displaced, and hence not sensed, a signal generated by the sensing mechanism inhibits a machine function logic control circuit inhibiting machine functions, such as the operation of an end cap staking mechanism. The signal further actuates a diverting mechanism for diverting the defective magazine, and an annunciator to alert the operator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
In a film detecting and magazine end cap staking mechanism for detecting an accurately positioned film end portion extending from a film magazine, and in response thereto staking an end cap onto the film magazine, the combination comprising: detecting means for detecting an accurately positioned film end portion extending from a film magazine and generating a predetermined signal in response thereto; and staking means responsive to said predetermined signal for staking an end cap onto a film magazine.
Claim 2
Dependent Claim
78 words
In a film detecting and magazine end cap staking mechanism for detecting an accurately positioned film end portion extending from a film magazine, and in response thereto staking an end cap onto the film magazine, the combination comprising: detecting means for detecting an accurately positioned film end portion extending from a film magazine and generating a predetermined signal in response thereto; and staking means responsive to said predetermined signal for staking an end cap onto a film magazine.
Claim 3
Dependent Claim
43 words
The invention according to claim 1 wherein said detecting means comprises a film sensor, and means for moving said sensor between a normal retracted position and a film sensing position in which it senses the edge of an accurately positioned film end portion.
Claim 4
Dependent Claim
19 words
The invention according to claim 2 wherein said moving means comprises an air cylinder coupled to said film sensor.
Claim 5
Dependent Claim
72 words
The invention according to claim 1 wherein said detecting means comprises a film sensor, and means for moving said film sensoR between a normal retracted position and a film sensing position in which it senses the edge of an accurately positioned film end portion, and said staking means comprises a staking mechanism, and a logic control coupled to said staking mechanism and responsive to said predetermined signal for operating said staking mechanism.
Claim 6
Dependent Claim
121 words
In a film detecting and magazine end cap staking mechanism for detecting a missing or inaccurately positioned film end portion extending from a film magazine and in response thereto inhibiting the staking of an end cap onto the film magazine, the combination comprising: staking means for staking an end cap onto a film magazine; detecting means for detecting an accurately positioned film end portion and generating a predetermined signal in response thereto, and generating a different signal when a film end portion is missing or inaccurately positioned; and logic circuit means coupled to said staking means and responsive to said different signal for inhibiting operation of said staking means so that an end cap is not staked onto said film magazine.
Claim 7
Dependent Claim
121 words
In a film detecting and magazine end cap staking mechanism for detecting a missing or inaccurately positioned film end portion extending from a film magazine and in response thereto inhibiting the staking of an end cap onto the film magazine, the combination comprising: staking means for staking an end cap onto a film magazine; detecting means for detecting an accurately positioned film end portion and generating a predetermined signal in response thereto, and generating a different signal when a film end portion is missing or inaccurately positioned; and logic circuit means coupled to said staking means and responsive to said different signal for inhibiting operation of said staking means so that an end cap is not staked onto said film magazine.
Claim 8
Dependent Claim
43 words
The invention according to claim 1 wherein said detecting means comprises a film sensor, and means for moving said sensor between a normal retracted position and a film sensing position in which it senses the edge of an accurately positioned film end portion.
Claim 9
Dependent Claim
19 words
The invention according to claim 2 wherein said moving means comprises an air cylinder coupled to said film sensor.
