Abstract
Abstract Plastic molding apparatus is disclosed for forming a series of molded connector bodies along a molded strip segment. By repeating the molding cycle, an additional strip segment is simultaneously molded and joined to a previously made strip segment, so that repeated cycling of the molding machine provides a molded continuous strip interconnecting a series of molded bodies.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A method for molding a series of molded products in continuous strip form, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one said die, withdrawing all but a remainder portion of said first molded product from between said dies, aligning said remainder portion in desired position between said dies, detecting misalignment of said remainder portion, preventing closure together of said dies when said misalignment is detected, closing together said dies over said aligned remainder portion, slackening said first molded product during closing together of said dies over said remainder portion, and molding a second molded product by said closed together dies while joining the second molded product integrally to said remainder portion.
Claim 2
Independent Claim
132 words
A method for molding a series of molded products in continuous strip form, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one said die, withdrawing all but a remainder portion of said first molded product from between said dies, aligning said remainder portion in desired position between said dies, detecting misalignment of said remainder portion, preventing closure together of said dies when said misalignment is detected, closing together said dies over said aligned remainder portion, slackening said first molded product during closing together of said dies over said remainder portion, and molding a second molded product by said closed together dies while joining the second molded product integrally to said remainder portion.
Claim 3
Independent Claim
123 words
A method for molding a series of molded products in continuous strip form, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one of said dies, withdrawing all but a remainder portion of said first molded product from between said dies, penetrating a pilot means into said remainder portion, preventing closure together of said dies over said remainder portion if said pilot means fails to penetrate said remainder portion, closing together said dies over said remainder portion if penetrated by said pilot means, molding a second molded product by said closed together dies and joining said second molded product integrally to said remainder portion.
Claim 4
Independent Claim
123 words
A method for molding a series of molded products in continuous strip form, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one of said dies, withdrawing all but a remainder portion of said first molded product from between said dies, penetrating a pilot means into said remainder portion, preventing closure together of said dies over said remainder portion if said pilot means fails to penetrate said remainder portion, closing together said dies over said remainder portion if penetrated by said pilot means, molding a second molded product by said closed together dies and joining said second molded product integrally to said remainder portion.
Claim 5
Independent Claim
112 words
A method for molding a series of products along a continuous flexible strip, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one said die, withdrawing all but a remainder portion of said first molded product from between said dies, penetrating a flexible strip portion of said remainder portion with a pilot means, closing together said dies over said remainder portion if penetrated by said pilot means, molding a second molded product by said closed together dies and joining the second molded product integrally to said flexible strip portion of said remainder portion.
Claim 6
Independent Claim
112 words
A method for molding a series of products along a continuous flexible strip, comprising the steps of: molding a first molded product by a closed together pair of molding dies, separating said dies, ejecting said first molded product from at least one said die, withdrawing all but a remainder portion of said first molded product from between said dies, penetrating a flexible strip portion of said remainder portion with a pilot means, closing together said dies over said remainder portion if penetrated by said pilot means, molding a second molded product by said closed together dies and joining the second molded product integrally to said flexible strip portion of said remainder portion.
Claim 7
Dependent Claim
33 words
The method as recited in claim 3, and further including the step of: Preventing closure together of said dies over said remainder portion if said pilot means fails to penetrate said remainder portion.
Claim 8
Independent Claim
42 words
The method as recited in either of claims 2 or 3, and further including the step of: Slackening said first molded product subsequent to penetration thereof by said pilot means and prior to closure together of said dies over said remainder portion.
Claim 9
Independent Claim
37 words
The method as recited in either of claims 2 or 3, wherein, said step of closing together said dies includes advancing said pilot means toward said remainder portion to penetrate said pilot means into said remainder portion.
