The dangers of unguarded machinery have been highlighted to public liability insurance holders after a worker suffered serious injuries to his hand.
Prospect Joinery, based in Stourbridge, pleaded guilty to breaching Section 2(1) of the Health and Safety at Work Act 1974 and was fined £3,000 with costs of £1,000.
Stourbridge and Halesowen Magistrates Court heard that David Bell, 59, from Wolverhampton, was making wooden beading by hand-feeding lengths of wood into a machine when the incident happened.
His hand became caught and the machine amputated his right hand index finger, broke his middle finger and gave him severe cuts.
John Glynn, Health and Safety Executive Inspector, said: "Prospect Joinery failed in its role to protect its workers by not properly guarding this machine. Mr Bell should never have been placed in the position he was."
Earlier this month, two London-based food firms, Kolak Snack Foods and Smith Weston, were prosecuted after a worker had his fingers severed while using a food mixing blender.
