Abstract
An apparatus has a rotatable base having a plurality of guide features with opposed sides and supports. Each of the supports are slidably disposed in one of the plurality of guide features. The supports and the base member have spacer engagement surfaces which are configured to face one another in pairs and to have spacers clamped between each of the pairs. The spacers are so dimensioned as to locate each of the supports in a predetermined position with respect to an axis of rotation of the rotatable base member. A gear train on cut drive side is driven by a variable speed motor. Motor speed can be set for a given can diameter.
Claims20
An apparatus comprising:
- a rotatable base member having a plurality of guide features with opposed sides;
- supports, each respective support slidably disposed in a different one of the plurality of guide features, the supports and the rotatable base member having spacer engagement surfaces;
- and
- spacers, each respective spacer configured to be clamped between one of the spacer engagement surfaces and a facing spacer engagement surface,
- wherein each spacer engagement surface on one of the supports or the rotatable base member forms a pair with a facing spacer engagement surface on the other of the supports and the rotatable base member,
- wherein the spacers are dimensioned to position each of the supports in a predetermined position with respect to an axis of rotation of the rotatable base member.
A trimmer apparatus comprising:
- a base member;
- a plurality of cartridge mounting arrangements each slidably supported on the base member so as to be each slidable toward a center of the base member, each cartridge mounting arrangement being adapted to operatively support a trimming cartridge having at least one cutting element;
- spacers which are disposable between portions of the cartridge mounting arrangements and portions of the base member to determine a position of the cartridge mounting arrangements with respect to the center of the base member;
- and
- fastening devices which are associated with each of the cartridge mounting arrangements and which are configured to engage the base member and selectively force the cartridge mounting arrangements toward the center of the base member so as to sandwich the spacers between the portions of the cartridge mounting arrangements and the portions of the base member.
A method of adjusting a trimming cartridge to a position suitable for a trimming a can having a given diameter, comprising:
- slidably supporting a support, which is configured to support the trimming cartridge, on a rotatable base;
- disposing spacers between opposed surfaces of the trimming cartridge and the rotatable base to locate the support in a predetermined radial position on the rotatable base;
- and
- tightening the support against the rotatable base so that the spacers are clamped between the opposed surfaces.
