Reciprocation apparatus including a guide assembly

A reciprocation apparatus comprising:

• a) a frame;
• b) a contact member;
• and
• c) a reciprocation assembly comprising:
• i) an elongated member adapted to reciprocate relative to the frame;
• and
• ii) a guide assembly adapted to guide the elongated member, the guide assembly including a main body portion and a removable cartridge, wherein the cartridge houses the contact member and is adapted to secure the contact member relative to the guide assembly, wherein the contact member is for dynamically interfacing with at least a surface of the reciprocation assembly, and wherein the contact member and cartridge are adapted for common insertion and removal relative to the main body portion of the guide assembly.

A can body making apparatus comprising:

• a) a frame;
• b) a ram supported relative to the frame;
• c) a drive assembly adapted to linearly reciprocate the ram relative to the frame;
• d) a can holding mechanism for holding a can blank;
• e) a die pack, wherein the ram member being operative to selectively contact and force a can blank held by the can holding mechanism through the die pack;
• f) a contact member;
• and
• g) a guide assembly adapted to guide the ram, the guide assembly comprising a main body portion and a cartridge removably attached to the main body portion, wherein the contact member is disposed in and restrained by the cartridge, and wherein the contact member and cartridge are adapted for common insertion and removal relative to the main body portion of the guide assembly.

A can body making apparatus comprising:

• a) a frame;
• b) a first contact member;
• and
• c) a reciprocation assembly comprising:
• i) a ram mounted for reciprocation relative to the frame;
• and
• ii) a guide assembly adapted to guide the ram for reciprocation relative to the frame and including a first removable cartridge adapted to restrain the first contact member to the guide assembly, wherein the first contact member is for dynamically interfacing with at least a surface of the reciprocation assembly.
