Abstract
Abstract A method for use in a continuous process for winding a photographic web element into a scroll and inserting such scroll into an open-ended double-chambered film cartridge body is disclosed. Winding is facilitated by a winding mechanism that accurately positions the leading end of the element with respect to a winding mandrel from which mandrel a completed scroll is advanced into the cartridge supply chamber a distance sufficient to center the free end of the element with respect to a heat sealing head. A core support member then so positions the cartridge takeup core axially within the cartridge takeup chamber that the core is aligned precisely with the free end of the element for staking thereto by means of the heat sealing head.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
The method of loading a web into a receptacle having a supply compartment, a takeup compartment, and a takeup core rotatably housed within said takeup compartment and comprising the steps of: forming said web into a wound scroll having a free web end; inserting said scroll into said supply compartment; inserting a support member into said takeup compartment in supporting relationship with said takeup core; attaching said free web end to said takeup core while said support member is in said supporting relationship with said takeup core; and withdrawing said support member from said takeup compartment.
Claim 2
Independent Claim
96 words
The method of loading a web into a receptacle having a supply compartment, a takeup compartment, and a takeup core rotatably housed within said takeup compartment and comprising the steps of: forming said web into a wound scroll having a free web end; inserting said scroll into said supply compartment; inserting a support member into said takeup compartment in supporting relationship with said takeup core; attaching said free web end to said takeup core while said support member is in said supporting relationship with said takeup core; and withdrawing said support member from said takeup compartment.
Claim 3
Dependent Claim
52 words
The method of claim 1 further comprising the additional steps of: providing means for attaching said free web end to said takeup core; positioning said scroll within said supply takeup compartment with respect to said attaching means; and positioning said takeup core within said takeup compartment with respect to said attaching means.
Claim 4
Independent Claim
141 words
The method of loading a photographic web into a photographic cartridge body of the type having means for use in defining a web supply compartment, a web takeup compartment and a takeup core mounted for rotation about and for movement along an axis within said takeup compartment means, said method comprising the steps of: forming said photographic web into a wound scroll having a free web end extending therefrom; inserting said scroll into said web supply compartment means of said cartridge body; inserting a support member into said takeup compartment means of said cartridge body in supporting relationship with said takeup core means; attaching said free web end to said takeup core means while said support member is in said supporting relationship with said takeup core means; and withdrawing said support member from said supporting relationship with said takeup core means.
Claim 5
Independent Claim
141 words
The method of loading a photographic web into a photographic cartridge body of the type having means for use in defining a web supply compartment, a web takeup compartment and a takeup core mounted for rotation about and for movement along an axis within said takeup compartment means, said method comprising the steps of: forming said photographic web into a wound scroll having a free web end extending therefrom; inserting said scroll into said web supply compartment means of said cartridge body; inserting a support member into said takeup compartment means of said cartridge body in supporting relationship with said takeup core means; attaching said free web end to said takeup core means while said support member is in said supporting relationship with said takeup core means; and withdrawing said support member from said supporting relationship with said takeup core means.
Claim 6
Dependent Claim
43 words
The invention of claim 3 wherein said forming step includes winding said web around a mandrel having an axis of rotation and wherein said inserting step includes the step of effecting relative movement between said mandrel and said scroll along said mandrel axis.
Claim 7
Dependent Claim
45 words
The invention of claim 3 wherein said web comprises a photosensitive web member and a superimposed backing web member so disposed with respect to said photosensitive web member as to form said free end of said web when said web is wound into said scroll.
Claim 8
Dependent Claim
57 words
The invention of claim 5 including the steps of: providing means for attaching said free web end to said takeup core means; positioning said scroll within said supply compartment means in predetermined relationship with respect to said attaching means; and positioning said takeup core means along its axis of rotation in predetermined relationship with said attaching means.
Claim 9
Dependent Claim
41 words
The invention of claim 6 wherein said web has a longitudinal axis and said attaching means includes a heating head having a central axis and wherein said scroll positioning step includes aligning said longitudinal web axis with said heating head axis.
Claim 10
Dependent Claim
40 words
The invention of claim 6 wherein said takeup core means includes a lateral axis and wherein said core positioning step includes placing said core means lateral axis in co-alignment with said heating head axis and with said longitudinal web axis.
Claim 11
Independent Claim
168 words
The method of loading a photographic web into a photographic cartridge body of the type having means for use in defining web supply and takeup compartments, a takeup core having an axis of rotation and disposed within said takeup compartment means, and spindle means for mounting said takeup core for rotation about and for movement along said core axis, said method comprising the steps of: forming said photographic web into a wound scroll having a free web end extending therefrom, providing means for attaching said free web end to said takeup core; inserting a support member into said takeup compartment means in supporting a relationship with said takeup core; inserting said scroll into said web supply compartment means and positioning said scroll and said takeup core in predetermined relationship with said attaching means; attaching said free web end to said takeup core while said support member is in said supporting relationship with said takeup core; and withdrawing said support member from said supporting relationship with said takeup core.
