According to the latest survey of primary processing equipment suppliers, optimism has occupied the part of machinery suppliers in the rubber industry. More than 63% of respondents this year said they expected sales to increase in 1994, while only 3% thought sales would fall. The remaining 34% of sales are expected to be flat from last year. The survey was answered by 70 machinery manufacturers. Half of the respondents said sales had increased over the past few years, 36% said sales remained unchanged, and 8% said sales had declined. Even after a period of low interest rates that have spurred machinery purchases in the past few years, many say the business environment is strong. Peter Day of Dieffenbacher said the company is now showing a dramatic improvement. Malcolm breith of MKB industries said, \"The economy seems to be improving despite rising interest rates . \". Of the companies that responded, 42% said more than half of their business was in the rubber industry. In the group, 73% expect sales to increase this year, while 64% say sales have been growing over the past few years. Less than 3% of the people who own most of the rubber industry expect sales to decline this year, while 11% of the group said sales have fallen in the past few years. Some other results from the survey showed that 65% of respondents also provided used and rebuilt equipment, while 82% provided Housing Reconstruction Service Among the used and rebuilt machinery suppliers surveyed, expectations for 1994 were similar, as 85% said sales would rise in 1994 and 77% said sales would rise in the past few years. Many return workers say that with the supply of good used equipment, especially printing machines and extrusion presses, \"paint brush rebuilders\" is still a problem in the industry.
