slats becoming loose. Cut the small slats
according to the length indicated on the design
drawings, and check the length of the slats
regularly to ensure that both ends are squared.
d. Hit & miss: on either vertical end of the slats may
lead to local loosening and poor adhesive force.
Strictly control the raw log specifications by
ensuring that the width and thickness are stable.
Workers in charge of planning and cutting the
slats must remove the defects of hit & miss as
well as the broken and cross grains for other
usage purposes.
e. Improper operation of the drill cutter: the milling
slots for the upper and lower rails are not
standardised, resulting in some of the small slats
becoming loose. Workers should set the milling
slots according to the design drawing of the
crib and ensure that the milling cutters stay sharp.
f. Non-standard gluing: insufficient and nonuniform
gluing in the drilled slots of the upper
and lower rails cause the crib’s rail to
become loose. Apply glue with a pneumatic
caulkinggun and ensure that the glue on the
inside of the drilled slots of the upper and lower
rails is sufficient and coated uniformly. Use a
two-component epoxy as the assembling glue
for the sliding rail in order to reach for the glue
solid content to reach 100%.
g. Unstable adhesive force due to paint: the
drilled slots of the upper and lower rails, and the
ends of the small slats arecovered with paint when
the crib parts are coated with oil. This results in
insufficient adhesive force after assembly.
Assemble the sliding rail before painting.
