A device or machine used for creating slots or openings, often in manufacturing or engineering contexts.
The engineer used a slotter to create precise slots in the metal sheet.
The word 'slotter' originates from the word 'slot' (from Middle Dutch 'slot', meaning a narrow opening or groove) and the suffix '-er' (meaning a person who). A slotter is a person or device that creates or uses slots.
Think of a 'slot' as a narrow opening and remember that a 'slotter' is someone who works with or creates these openings.
