Udbredelsen af String-maskiner i Danmark, var anledning til en debat på det ordinære repræsentantskabsmøde den 19. marts om DBwF’s gennemførsel af DBwF’s mesterskaber, stævner og turneringskampe på String-maskiner. Debatten endte med, at der var et behov for en revision af DBwF’s spilleregler.
Siden har en arbejdsgruppe arbejdet med indsamling af erfaring ved at brug af String-maskiner. Samtidig har IBF i forbindelse med World Games i juli, udsendt ”regler for, hvornår en kegle er væltet”.
Det giver anledning til følgende præcisering om væltede kegler på String-maskiner:
- Snoren er en del af keglen. Hvis en kegle væltes af snoren fra andre kegler, betragtes den for væltet.
- Registrering af keglefaldet slutter, når skjoldet begynder at gå ned. Eventuelt keglefald der sker efter at skjoldet begynder at gå ned, er ikke væltet korrekt og skal genrejses.
- Hvis en kegle registreres som væltet, men det er tydeligt, at keglen ikke er væltet korrekt, fx hvis den er rykket til en anden plads, skal den genrejses, og registreringen rettes.
- Hvis keglen ikke er registreret som væltet, men alle er enige om, at keglen væltede korrekt, så skal registreringen rettes.
- Hvis de to klubber ikke kan blive enige, tilkaldes dommeren, der om muligt træffer en afgørelse, eller om der skal spilles en provisorisk kugle eller rude.
- Hvis en kegle rykker sig til anden plads, men bliver stående, genrejses den automatisk på sin oprindelig plads. Keglen skal derfor, til forskel fra reglerne for Fritfaldsmaskiner, stå på sin oprindelige plads.
- Hvis en kegle står i renden, kan den registreres som ikke væltet af maskinen. Keglen skal fjernes og registreres som væltet, da den har forladt banen.
Redaktionelle ændringer af spillereglerne jf. DBwF’s love § 9, stk. 4.1.2, samt opdatering af dommerhåndbogen er gennemført.

Pinfall Action Rule to Follow
Bowlers are used to free-fall machines and pinfall behavior associated with them. Overall the pinfall
action on EDGE String is very close to free-fall machines but there are some spare and split leave
situations where strings may come into play, resulting in slightly different pinfall compared what
bowlers may be used to with free-fall machines. This is simply the physics of the pins being on
strings. Everyone is bowling on the same playing field. No score corrections will be granted for pinfall
that is due to the physics of string machines.
Allowed Score Correction Scenarios
Free-Fall machines typically use cameras to read pinfall. While very reliable, there are times when
cameras miss-core and a score correction is needed. Bowlers are used to this. String machines don’t
use cameras, rather they use sensors on each string that tell the machine which pins fell based on
how much string moved past the sensors. This is a reliable and robust system as well, however, just
as with scoring cameras, there are situations where string machines may miss-score. These don’t
happen frequently but can happen and bowlers may not be used to seeing these. Below are the
situations to be aware of, that if occur, a score correction will be required.
- Corner pin slides into the gutter, remains standing or leaning against kickback, gets
scored as standing but should be scored as fallen
This can happen if not enough length of string moves for the machine to count the pin as
fallen. This situation can happen on free-fall machines too because sometimes the
camera does not pick these up correctly.
- A pin slides across the deck and remains standing but get scored as fallen
This can happen if enough length of string gets pulled during the sliding movement to
make the machine think the pin fell and so it scores it as having fallen.
- A pin remains solidly standing but the machine scores it as fallen
This can happen if the string on a flying pin hits the string on another pin, moving that
pin’s string enough for the machine to think the pin fell, but the pin did not actually fall.
An example of this would be a bowler gets awarded a strike but the 10-pin clearly
remained standing.
Rule to Follow for End of Scoring Cycle
With free-fall machines the universal visual indictor that the scoring cycle has ended and no more
pinfall should count towards score is when the table reaches the top of the pins, as the machine is
cycling to pick up pins. Bowlers are used to this. With string machines there is no table that comes
down to signal visually to bowlers that the scoring cycle is over, so there may be some confusion as
to when the scoring cycle ends, especially since many bowers are not used to string machines. To
prevent this, the following rule should be communicated to bowlers and followed:
- The scoring cycle is over as soon as the machines begins to cycle (visually seen as the
shield starts moving to come down)
- Any pinfall that appears to occur after the pin shield begins to lower does not count
towards the score
