Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
In a blow-molding apparatus, the combination comprising a support structure, an extruder head fixed relative to said support structure, a mold for receiving a parison from said extruder head, mounting means comprising at least one supporting member for movement of said mold into and out of the path of a parison extruded by said extruder head, said supporting member supporting said mold and being supported by at least two guide members hingedly connected at one end to said supporting member and at the opposite end to said support structure, said guide members being disposed successively in the direction of motion of said mold, whereby said mold is alternately moved in an arced path from one position beneath said extruder head to an adjacent poSition alongside such extruder head, and both of said positions residing in a common plane through said mold.
Claim 2
Dependent Claim
141 words
In a blow-molding apparatus, the combination comprising a support structure, an extruder head fixed relative to said support structure, a mold for receiving a parison from said extruder head, mounting means comprising at least one supporting member for movement of said mold into and out of the path of a parison extruded by said extruder head, said supporting member supporting said mold and being supported by at least two guide members hingedly connected at one end to said supporting member and at the opposite end to said support structure, said guide members being disposed successively in the direction of motion of said mold, whereby said mold is alternately moved in an arced path from one position beneath said extruder head to an adjacent poSition alongside such extruder head, and both of said positions residing in a common plane through said mold.
Claim 3
Dependent Claim
33 words
The blow-molding apparatus according to claim 1, including crank linkage means to effect alternate movement of said mold from a position beneath said extruder head to an adjacent position alongside said extruder head.
Claim 4
Dependent Claim
36 words
The blow-molding apparatus according to claim 2, including a second mold for receiving a parison from said extruder head during the time said first or other mold is in said adjacent position alongside said extruder head.
Claim 5
Dependent Claim
70 words
The blow-molding apparatus according to claim 3, including mounting means comprising at least one supporting member for movement of said second mold into and out of the path of a parison extruded by said extruder head, said supporting member supporting said second mold and being supported by at least two guide members hingedly connected at one end of said supporting member and at the opposite end to a fixed location.
Claim 6
Dependent Claim
56 words
The blow-molding apparatus according to claim 4, wherein said extruder head is fixed relative to said support structure and opens downwardly for extruding a vertically depending parison, and said molds alternately receiving a parison from a position beneath said extruder head and alternately being positioned for the subsequent blow-molding of said parison alongside said extruder head.
Claim 7
Dependent Claim
19 words
The blow-molding apparatus according to claim 1, wherein said guide members are disposed parallel with respect to each other.
