A Multi Direct Drive gob distributor to reduce defects A distributor system for all gob configurations has been designed and developed by BDF Industries to offer glass producers high speed and superior quality performances.
This is particularly true in outer sections of the machine where eventual positioning errors due to non-independent scoop motion has a more significant impact, in relative terms, as compared to inner sections. Years of experience in the hollow glass market has allowed us to affirm that scoop-trough misalignment is often the cause of compromised solutions, which subsequently lead to less than optimal gob delivery. In many cases, the gob collides and impacts with the trough as it exits the scoop, consequently slowing down and deforming in an anomalous manner, thus resulting in defective or low-quality products. There are difficulties associated with gob delivery in outer sections of machines with 10 or more sections, subsequently resulting in defective products. The Multi Direct Drive gob distributor guarantees perfect and repetitive alignment between every single scoop and relative trough, for both central and
outer sections. The transfer of gobs on to relative troughs is fluid and repetitive, thus eliminating energy losses due to impact and allowing a higher gob speed in the trough.
Motor and drive system BDF’s Multi Direct Drive gob distributor is distinguished from those currently available in the market insofar as every single scoop is controlled by its own motor and direct drive system, without intermediate elastic elements: this means every single scoop and its relative positioning is totally independent of the others. Other defining and particularly appreciated features include entirely independent programming and the absolute repeatability of individual positions based on the selected and Continued>>

T
he end quality of a glass container depends on the efficiency of the gob distributor and delivery system, consisting in a scoop-trough and deflector. That is why BDF Industries has sought to improve its current technology, working to develop a faster and more consistent flow to improve gob delivery to the machine and guarantee high thermal consistency, all determining factors in ensuring the high quality of finished glass containers. The Multi Direct Drive gob distributor constitutes one of the most important components in the BDF Industries’ Forming range of products. It has been patented directly by the internal Technical Department in single, double, triple and quadruple gob configurations for all known machine types and has been carefully designed and developed to offer glass producers high speed and superior quality performances. The innovation was inspired by the desire to introduce a more reliable, highperforming system into the market with respect to those currently available. Traditional gob distributors are renowned for presenting a number of difficulties when it comes to perfectly aligning the scoop and trough.
