Definitions
- the present invention generally relates to weather strips and,
- Weather strips of this type are typically extruded from
- EPDM ethylene-propylene-diene
- the extruded weather strip may be cured by heat and then cooled in a water
- desired location such as between the trunk frame and the trunk lid, or at other
- strip may be permanently thermoformed during the manufacturing process into
- tubular foam plugs 1 8 are shown in Fig. 1 . As shown in Fig. 1 , various types of tubular foam plugs 1 8 are
- tubular plugs 1 8 are usually about 4-8
- Fasteners such as rivets (not shown), may be punched
- the plugs also may be fastened by other means, such as
- manufactures may position a clamp at the desired location along tne weather strip to function as
- the invention generally relates to a method of
- thermoplastic liquid into the hollow interior of a compressible bulb member.
- the liquid thermoplastic material at least partially cures into a resilient plug
- the liquid thermoplastic material is a hot
- melt material and, more specifically, a tool dip like hot melt material which
- the liquid thermoplastic material may De mjec ⁇ e ⁇ oy first forming
- the hole may be formed
- compressible bulb member is formed preferably by extruding EPDM.
- thermoplastic material is preferably injected only along a portion of the length
- the bulb member and, more preferably, at a portion or portions of the length
- the invention further contemplates a weather strip comprising a
- compressible bulb member having a hollow interior and a resilient
- thermoplastic material located in the hollow interior.
- the weather strip can be any thermoplastic material located in the hollow interior.
- Fig. 1 is an elevational view, partially cross sectioned, illustrating
- FIG. 2A is an elevational view, partially cross sectioned
- Fig. 2B is a cross sectional view taken along line 2B-2B of Fig.
- Fig. 3A is an elevational view, partially cross sectioned
- Fig. 3B is a cross sectional view taken along line 3B-3B of Fig.
- thermoplastic hot melt material from a heated hose 32 and
- valve 36 having a discharge portion
- Discharge portion 38 may be constructed so as to
- Channel 1 6 adjacent to carrier or channel 1 6.
- Channel 1 6 is a relatively rigid
- a hole may be preformed through
- Hot melt material 34 is preferably injected along only a portion of
- weather strip 10 such as along a portion that is or will later be
- pressure points or areas of higher stress concentration may also utilize the
- liquid hot melt material 34 may be sealed off on both ends thereof,
- clamps for example, by applying clamps (not shown) or through other methods.
- the hot melt material 34 may spread
- the hot melt material 34 may be introduced at one or more locations
- fixturing may be provided to hold and
- bulb member 1 2 from expanding diametrically and, as a result, either splitting or lessening the lengthwise movement of hot melt material 34 along bulb
- non-reinforced areas of weather strip 10 Preferably, for automotive
- plug 40 will increase the force to compress bulb member 1 2 by
- the reinforced area is still resilient enough to allow weather strip
- plug length of about 1 00mm to about 400mm is preferred, however, this may
- thermoplastic materials such as other thermoplastic materials
- solid hot melt materials may be used instead.
