Method and apparatus for deflashing hollow plastic articles

Claim 2

In a process for deflashing the neck of hollow plastic articles, after they have been released from the mold in which they were fabricated and partially cooled, which process includes cutting off the neck flash of each such article gradually by a cutting component while causing the hollow article to execute a translational movement while maintaining its axis perpendicular to the cutting component, and a rotational movement about its longitudinal axis, The improvement comprising: removing each cutoff flash from the cutting component by removal means; and removing each article whose flash has not been completely cut-off from the cutting component by the same removal means.

Claim 3

In a process for deflashing the neck of hollow plastic articles, after they have been released from the mold in which they were fabricated and partially cooled, which process includes cutting off the neck flash of each such article gradually by a cutting component while causing the hollow article to execute a translational movement while maintaining its axis perpendicular to the cutting component, and a rotational movement about its longitudinal axis, The improvement comprising: removing each cut-off flash from the cutting component by removal means; and removing each article whose flash has not been completely cut-off from the cutting component by the same removal means.

Claim 4

In a process for deflashing the neck of hollow plastic articles, after they have been released from the mold in which they were fabricated and partially cooled, which process includes cutting off the neck flash of each such article gradually by a cutting component while causing the hollow article to execute a translational movement while maintaining its axis perpendicular to the cutting component, and a rotational movement about its longitudinal axis, The improvement comprising: removing each cut-off flash from the cutting component by removal means; and removing each article whose flash has not been completely cut-off from the cutting component by the same removal means.

Claim 5

a cutting component for cutting off the neck flash from each such article;

Claim 6

a cutting component for cutting off the neck flash from each such article;

Claim 7

means disposed for causing each such hollow article to execute a translational movement while its longitudinal axis remains perpendicular to said cutting component;

Claim 8

means disposed for causing each such hollow article to execute a translational movement while its longitudinal axis remains perpendicular to said cutting component;

Claim 9

A process as defined in claim 1 wherein the removal means including a gripping component for gripping each neck flash and said steps of removing are carried out by conveying cut-off neck flashes and articles which have been completely deflashed away from the cutting component along respectively different paths.

Claim 10

A process as defined in claim 2 wherein the gripping component acts directly only on the neck flashes.

Claim 11

means disposed for causing each hollow article to execute a rotational movement about its longitudinal axis while subject to the action of said cutting component;

Claim 12

means disposed for causing each hollow article to execute a rotational movement about its longitudinal axis while subject to the action of said cutting component;

Claim 13

means for conveying each completely deflashed article along a path away from said cutting component; and

Claim 14

means for conveying each completely deflashed article along a path away from said cutting component; and

Claim 15

A process as defined in claim 2 further comprising causing the gripping component to grip each neck flash before it passes through the cutting component.

Claim 18

gripping components disposed for grasping each neck flash and for carrying it away, after passing through said cutting component, along a different path from that followed by the completely deflashed hollow articles.

Claim 19

gripping components disposed for grasping each neck flash and for carrying it away, after passing through said cutting component, along a different path from that followed by the completely deflashed hollow articles.

Claim 20

An arrangement as defined in claim 5 further comprising a rotary support and wherein said gripping components are composed of a plurality of combinations, with each said combination including: at least one fixed arm attached to said rotary support; at least one mobile arm attached to said rotary support; at least two wheels mounted on said fixed arm; at least one wheel mounted on said mobile arm; and means for moving said mobile arm relative to said fixed arm for causing a flash to be imprisoned between said wheels.

Claim 21

An arrangement as defined in claim 6 wherein said wheels of each said combination are situated in one and the same plane.

Claim 22

An arrangement as defined in claim 6 each said wheel of each said combination has a rim which is profiled according to the profile of the neck flash to be removed.

Claim 23

An arrangement as defined in claim 6 wherein said at least one wheel is mounted at one end of its said mobile arm and said means for moving said mobile arm comprises a cam control unit arranged to act on the opposite end of said mobile arm.

Claim 24

An arrangement as defined in claim 6 wherein said means for causing each article to execute a rotational movement include means for causing at least one of said wheels of each said combination to rotate continuously about its axis.

Claim 25

An arrangement as defined in claim 10 wherein said cutting component comprises a circular cutting blade connected to said at least one of said wheels for rotation therewith.
