Title: Dispensing thermoplastic spacers into mastic seals - e.g. for sealing glass into metal window frames to prevent mastic displacement by winds (SW221176)
Inventor: LAMB ROBERT COLIN
IPC: E04F21/28
Filed: 1976-09-01
Abstract: Spacer elements comprise a long flat array of short blocks or columns linked by integral semi-rigid tie bars. A device resembling a stapling machine is used to dispense transverse rows of linked blocks from stock strip loaded from a magazine and advanced stepwise by the dispensing machine. Pref. the spacers are made of polyacetal or of ABS copolymers but may be of other thermoplastics inocorporatin glass or mineral fillers. Esp. for incorporation of spacers at intervals into relatively soft (polybutylene) mastics as used for sealing glass into metal window frames. The spacers limit progressive compression and displacement of the mastic, viz. by successive wind gust pressures, which otherwise could eventually expel sufficient mastic for the glass to become unsealed and/or loose in its frame. Typically, linked pairs of rows of blocks are embedded in the mastic. The spacers are firm enough to provide support, not hard enough to damage adjacent glass, are resistant to moisture and do not corrode.
